It didn't last long, but there was a moment earlier this week when I 
was sure Microsoft would unveil its own laptop. At a press event, 
Surface chief Panos Panay took the stage to remind the reporters in 
attendance how they once said tablets would make laptops obsolete. A 
quick scan around the room revealed rows of journalists, all typing on 
Ultrabooks -- including the MacBook Air, no less. For a moment, it 
seemed like Panay was conceding defeat.
Indeed, Microsoft has had multiple chances to prove it can bridge the
 divide between slates and laptops: Both the first- and second-gen 
Surface tablets were intended as do-it-all devices. And both times, the 
company fell short of its mission. The 
 in particular was powerful enough to rival Ultrabooks, but suffered 
from several usability flaws: It was awkward to use in the lap, and also
 unwieldy as a tablet. For most people, a touchscreen laptop was still 
the better choice.
Even so, that wasn't Panay conceding defeat up there on stage -- that
 was him being persistent. When he finally did get to the point, he 
unveiled not a laptop, but a tablet, the 
.
 Most notably, this third-gen device steps up to a larger, 12-inch 
screen, bringing it in line with contemporary Ultrabooks. The keyboard 
has been born again too, this time with a larger, more responsive 
touchpad and the ability to prop it up at a more comfortable angle. As a
 tablet, meanwhile, the Surface Pro 3 is thinner and lighter than the 
,
 despite having a bigger display. Just as important, the device will 
start at $799 when it goes on sale next month -- that's a hundred 
dollars less than last year's model. All told, the Surface Pro 3 is 
Microsoft's biggest, fastest, thinnest, lightest, best tablet yet. Panay
 even went so far as to say, "Today we take the conflict away." Did 
they, though?
  Summary
  The Surface Pro 3 is Microsoft's biggest and best tablet yet, but it needs a better keyboard to truly replace your laptop.
Hardware
Physically speaking, the Surface Pro 3 has more in common with the 
Surface 2,
 which runs Windows RT, than with previous Surface Pros. This year, 
Microsoft ditched the old carbon-black color in favor of a more playful 
silver, though the chassis itself is still made of sturdy magnesium 
alloy, with chamfered edges making it easy to wrap your fingers around. 
It's not just the color, though, that makes me think of the Surface 2: 
The Surface Pro 3 measures just 0.36 inch thick, making it only a tad 
fatter than the Windows RT model; that guy comes in at 0.35 inch wide. 
This is stunning when you remember the Surface 2 is a traditional 
tablet, comparable to the iPad, whereas the Surface Pro is basically an 
Ultrabook without a built-in keyboard. In fact, Microsoft says this is 
the thinnest machine with an Intel Core i7 processor. It may also be the
 lightest too, at 1.76 pounds. And even if it's not, it's still a 
meaningful improvement -- both the first- and second-generation Surface 
Pros weighed two pounds.
The Surface Pro's thinness seems even more impressive when you 
compare it to its peers: full-fledged Ultrabooks. Most 13-inch Ultras 
come in at around three pounds and half an inch thick (if they're 
lucky). Even the 
11-inch MacBook Air,
 which benefits from a smaller footprint, tips the scales at 2.38 
pounds. Next to those systems, the Surface Pro 3 is impossibly compact. 
In fact, I was loath to go back to my 13-inch MacBook Air after my 
review was over; the new Surface is just so much lighter. Truly, why 
can't all Ultrabooks be this easy to carry?
As a tablet, of course, the Surface Pro still doesn't feel particularly light; you don't just 
forget
 what it feels like to use a lighter device like the iPad Air. That 
said, it's definitely lighter than a 12-inch tablet has any right to be.
 Also, there's this: Despite that bigger screen -- or maybe 
because
 of it -- the Surface Pro 3 handles better than its predecessors. For 
one thing, blowing up the screen size actually allowed Microsoft to slim
 down the proportions. Think about it: With more internal space to work 
with, the engineers were able to rearrange the components, laying some 
items side by side instead of stacking them on top of each other. The 
result is a substantially thinner device that might not have been 
possible had Microsoft stuck with a 10.6-inch screen size.

Additionally, the new Surface Pro has a different aspect ratio: 3:2, 
instead of the usual 16:9. During his keynote, Panay said the company 
was actively trying to mimic the dimensions of a legal pad, the sort of 
object humans are already used to holding, and working with. It was a 
smart move, I think: With this new shape, the tablet feels less 
top-heavy in portrait mode, and it's easier to reach things with your 
thumbs in landscape. Goes to show that weight reduction isn't everything
 (though it definitely helps).
As it is, the Surface 2 and Surface Pro 2 have dual-stage kickstands 
that can be arranged in one of two positions. The Surface Pro 3 goes a 
step further -- literally -- with an option to pull out the kickstand at
 a near-flat 150-degree angle. This is useful if you're playing a board 
game or using a drawing app, and an upright angle won't do. All in all, 
too, the kickstand feels well-built, if a little rigid. Granted, I 
wouldn't want the hinge to move so easily that it verges on snapping 
off. But the kickstand here is so tightly wound that I actually feel a 
bit naughty every time I push it back into that 150-degree position; 
there's so much friction that when I push the stand back, I feel like 
I'm doing something I'm not supposed to. It's also still a bit awkward 
to pull the kickstand out, since there's only a notch on one side of the
 tablet. Again, though, it feels durable, and still makes that soft 
"click" sound every time you snap it shut.
Despite the bigger size, the port selection is the same as ever. That
 means: a power button on the top landscape edge; a Mini DisplayPort and
 USB 3.0 connection on the right; and a volume rocker and headphone jack
 on the left. The bottom, of course, is home to the magnetic guides that
 allow it to click into the optional Type Cover keyboard (more on that 
in a moment). There's also a microSD slot tucked under the kickstand, 
supporting cards as large as 128GB. Microsoft also upgraded the cameras 
so that both go up to 5-megapixel resolution. Meanwhile, there's a 
proprietary charging port on the right side, just below the USB socket. 
Though the charger stays put, it's still awkward to insert -- a minor 
annoyance you'll surely get used to, should you choose to buy this. As 
for the front-facing speakers, said to be 45 percent louder than last 
year's model, they pass my "Dolly Parton rundown test" with flying 
colors. (They make other kinds of music sound good, too.)
Display and pen input
The Surface tablets have always had lovely displays, and the 
third-gen Pro is no exception. What we have here is a 12-inch, 2,160 x 
1,440 IPS panel, with text so sharp you'd have to put your nose up 
against the screen to see any pixels. Colors are punchy, but balanced, 
and the viewing angles are good too, though even a low-glare screen like
 this isn't immune to reflections from overhead light. In general, I had
 little trouble reading the screen, but using the Surface in my lap was 
sometimes challenging; the most stable kickstand position doesn't 
necessarily mean the best viewing angles.
Under the hood, Microsoft used some different pen technology this 
time around: an active digitizer made by N-trig, as opposed to Wacom. 
While it might sound like I'm harping on specs there, hear me out: 
You'll be making some trade-offs. On the one hand, Wacom's digitizer 
offered more nuanced pressure sensitivity: 1,024 degrees, versus 256 
from N-trig. On the other hand, N-trig's setup allows for a thinner 
glass display and thus, a slimmer overall design. Additionally, N-trig's
 pen was designed to feel more like a proper, ink-based pen, and is 
therefore more natural to hold. Likewise, the screen has just enough 
friction that drawing on it feels more like dragging a pen across a pad 
of paper -- or as close as you can get, anyway. Personally, I'd choose a
 thinner, lighter device over more precise pressure sensitivity, but 
hey, don't let me set your priorities for you.
As you're using the pen, you'll notice it does some old tricks, along
 with some new ones too. It supports hovering, for instance, and you can
 use the top button as an eraser in select apps. On a more surprising 
note, you can press that top button to wake the tablet from sleep, at 
which point OneNote will open above the lock screen. Kind of like how 
you can already use the camera app from the Windows 8.1 lock screen. 
Also, OneNote now sends your scribbles to the cloud as you're writing 
them -- not unlike how you'd expect Google Drive to immediately save 
your work.
As with previous Surface devices, there's no place on the tablet to 
stow the pen. Rather, you're supposed to slip it inside a loop that 
attaches to either the Surface or the optional Type Cover keyboard. 
Unfortunately, the thing fell off after just a few days of use, which 
means you're probably on your own when it comes to making sure you don't
 lose your writing implement.
Typing experience
Just so you know, I'm typing this sentence from a Surface Pro 3. The 
thing is sitting in my lap, even. And you know what? I'm doing alright. 
This isn't my favorite laptop keyboard -- not by a long shot -- but I'm 
doing OK. And I think you will too. But before I get ahead of myself, 
let me explain what you're getting here. The first thing you should 
know, perhaps, is that there's just one keyboard option: a backlit Type 
Cover keyboard built specifically for the Surface Pro 3's bigger frame. 
For now, at least, the flat 
Touch Cover keyboard is not an 
option. Frankly, I always preferred the physical buttons anyway, just 
because the learning curve is so much smaller. The only thing you'll 
miss, maybe, is the Touch Cover's lighter-weight design. But given the 
choice, I'll take a more natural typing experience over a lighter 
keyboard any day. And hey, the tablet's already pretty light; you can 
deal with a few extra ounces.
What I like best about this new keyboard is that I don't have to type
 on a completely flat surface if I don't want to. Unlike previous Type 
Covers, this one has a magnetic strip on the top, allowing you to fold 
up the upper piece of the keyboard so that it attaches firmly to the 
tablet's lower bezel. The end result is sort of a wedge profile, similar
 to what you'd find on a proper laptop. And it goes a long way in making
 the thing more comfortable to use. Mind you, nobody's forcing you to 
pick the propped-up option; you can go flat if you want to. I just don't
 understand why anyone would.
The problem is that the keyboard is flimsy, and it's nowhere as 
sturdy or comfortable as "real" keyboards. As I type this, I can see the
 keyboard cover giving a bit under the weight of my fingers; it's enough
 to make me not want to use it in my lap (though I do it anyway, out of 
necessity). With every keystroke, I make a loud "clack," letting anyone 
around me know I'm 
getting stuff done. The keys are also 
bunched close together -- the opposite of your standard chiclet layout. 
That means it's a little too easy to hit the wrong key. Luckily for me, I
 have a copy editor, so you can't tell how many typos I actually made 
while writing this review. Suffice to say, it was enough that I 
eventually started to type more gingerly, in the hopes I wouldn't make 
quite as many mistakes.
The Surface Pro 3's Type Cover also brings an improved touchpad. And that's good timing, because the latest 
Windows 8.1 update
 made the OS much more mouse-and-keyboard friendly. In brief, the 
trackpad here is bigger, with a built-in touch button you can press down
 on. It's also said to be more responsive, but I'll be the judge of 
that, not Microsoft. Even if the trackpad is more precise than it used 
to be, it's still many steps behind the sort of glass touchpad you'd 
find on the MacBook Air or many Windows Ultrabooks. It sometimes takes 
multiple tries to get two-finger scrolling to work. Ditto for clicking 
and dragging windows and other objects around the screen. Other times, I
 accidentally navigated backward out of a web page when I was really 
trying to do some other sort of gesture. If you're serious about having a
 mouse, especially in desktop mode, you might be better off using a 
Bluetooth one, especially if you intend the Surface Pro to be your daily
 driver.

Make no mistake: When it comes to performance, the Surface Pro has 
always
 been able to go head to head with traditional laptops. Still, it's nice
 to know that as other Ultrabooks have experienced modest performance 
gains, Microsoft has kept pace. Armed with a Haswell processor (a 1.9GHz
 Core i5-4300U chip), 8GB of RAM, a Samsung-made solid-state drive and 
the usual Intel HD 4400 graphics, the Surface Pro 3 holds its own in 
synthetic benchmark tests, with scores that fall in line with the 
competition. It also boots quickly, taking just 10 seconds to get to the
 lock screen and then one more to load the Start Screen. My WiFi 
connection was consistently fast too, thanks to the 802.11ac radio 
inside (there's also Bluetooth 4.0, if you need it).
Accordingly, the Surface Pro 3 can do everything an Ultrabook can do.
 One of my favorite things about working on a Windows machine is the 
Snap feature, so I routinely have two programs laid out side by side -- 
usually Chrome and HipChat. In particular, I often have a dozen tabs 
open at once, including Gmail, my calendar, Engadget, Facebook, Twitter 
and the publishing software we use to write stories, not to mention the 
odd Wikipedia page and music-streaming service. In addition to the usual
 multitasking, you could also edit photos if you wanted, or maybe even 
cut together some video.
Throughout, the metal surfaces stayed relatively cool, and I didn't 
hear much noise coming out of the thin vent that surrounds the perimeter
 of the device. As with every other Ultrabook, though, the new Surface 
wheezes a bit during gameplay. Load up a game and the thing gets quite 
warm -- almost hot -- to the touch. Hot and noisy, too. At one point, 
the fans started exhaling so loudly that I heard them even in a loft 
space with various coworkers milling around nearby. If I can hear it 
over all that ambient noise, well, that's not good. Fortunately, it 
takes a lot to make the system pipe up like that. And if you do, it 
could be that you're doing something Ultrabooks weren't actually 
designed for.

Microsoft describes the Surface Pro 3's battery life in two ways: You
 can get up to nine hours of web surfing (WiFi on, auto-brightness 
turned off), 
or you can simply expect a 15 to 20 percent 
increase over previous models. Translation: Your mileage will vary, but 
battery life will be improved either way. And improved it is. In our 
video-looping test (also with WiFi on and auto-brightness disabled), the
 tablet managed seven hours and eight minutes. Compare that with the 
Surface Pro 2, which couldn't crack six and a half hours.
Now, let's put that seven-hour battery life in context. In short, 
it's not great, but it's not bad, either. Other ultraportables that are 
either small in size or super lightweight have tended to last a similar 
amount of time (see: the 
Acer Aspire S7-392 or the 
Sony VAIO Pro 11). Even some larger Ultrabooks, like 
Lenovo's Yoga 2 Pro and 
ThinkPad X1 Carbon,
 deliver less runtime despite having room for bigger batteries. The 
thing is, of course, there are many Ultrabooks that last much, much 
longer on a charge. The 
HP Spectre 13, 
Sony VAIO Pro 13, 
Sony Duo 13 and 
Samsung ATIV Book 9 Plus
 all last around eight and half hours, if not closer to 10. (The MacBook
 Air can go even longer, though I've never tested the 11-inch model.)
Though the Surface Pro 3 is lacking in battery life compared to 
larger Ultrabooks, it at least charges quickly. After pushing the 
battery to its limits, I got back up to 72 percent in around 90 minutes.
 So, even if you only have a short time to recharge, you should still 
recover enough juice to last you through a couple hours of work. And by 
the time 
that runs out, you probably will have found another outlet.
Update: After continued testing, we started to get 
even higher benchmark scores for the Surface Pro 3. We've updated the 
above benchmark table to include those.
Configuration options and the competition
The Surface Pro 3 can be either sorta expensive or really expensive, 
depending on the specs you choose. At the low end, there's a Core i3 
model with 64GB of storage, priced at $799. The next step up is a Core 
i5 configuration with 128GB of storage; that'll sell for $999. To get 
that same Core i5 unit with 256GB of storage instead, you'll pay $1,299.
 Rounding out the list are two Core i7 models: one with 256GB of storage
 and the other with 512GB. Those will cost you $1,549 and $1,949, 
respectively. As of this writing, the two Core i5 models were slated to 
ship on June 20th. The Core i3 and Core i7 configurations, meanwhile, 
aren't shipping until August 31st, according to Microsoft's online 
store. Either way, you can pre-order any of them now, if you like.
Unfortunately, whichever you pick, the $130 Type Cover keyboard is 
sold separately, which means the Surface Pro 3 immediately suffers in 
comparisons with proper Ultrabooks, like the Yoga 2 Pro ($1,199), Dell 
XPS 12 ($1,000), Acer Aspire S7-392 ($1,300) and the Samsung ATIV Book 9
 Plus ($1,400). For instance, if you wanted the Surface Pro 3 with a 
Core i5 processor, 8GB of RAM and a 256GB SSD, you'd pay $1,299 for the 
laptop and $130 for the keyboard, for a total of about $1,430. The Yoga 2
 Pro with comparable specs is currently going for $1,399, with an online
 price of $1,199.
And there's the rub: With a subpar keyboard, how can the Surface Pro 
truly be a laptop killer? And if the idea is for the Surface Pro to go 
head to head with Ultrabooks, the keyboard should also be included 
gratis. But it's especially bad if that $130 keyboard isn't even that 
comfortable to type on. So what do you end up with, then? A device 
that's slightly more expensive than comparable laptops, with an inferior
 typing experience. When you put it that way, it's tough to give this a 
glowing recommendation.
Wrap-up
With each generation of Surface devices, Microsoft gets closer to 
building a device that can replace both your tablet and laptop. 
Unfortunately, though, the company's progress has been gradual, and even
 after three attempts, it still hasn't addressed some serious usability 
flaws. This time around, the biggest problem is the keyboard. It's tough
 to say who should buy the Surface Pro 3 as a laptop alternative when 
the very thing that makes it a notebook replacement -- its optional 
keyboard -- offers a subpar typing experience and a frustrating 
trackpad. Adding insult to injury, it's not even included in the box; 
it's an optional $130 accessory that helps drive up the cost compared to
 similar PCs.
The good news is that despite its larger screen size, the Surface Pro
 is easier than ever to use as a tablet, thanks to a thinner, lighter 
design and more sensible aspect ratio. If Microsoft could just figure 
out the keyboard thing (and start throwing it in for free), I'd be more 
inclined to recommend this as a laptop replacement. For now, unless you 
want a tablet and laptop in equal measure, and sincerely enjoy using 
Windows Store apps, a touchscreen Ultrabook is still your best bet.
