Microsoft Surface Pro Review

Despite having an integrated 42 Wh battery (similar in size to the 3rd and 4th gen iPads with Retina Display), battery life is a real sore spot for Surface Pro. Haswell is really designed to drive platform power down to very low levels, which should help close the gap between ARM/Atom based tablets and Core based tablets. Unfortunately, Haswell for tablets won’t hit until the third quarter of this year, which forced Microsoft to use Ivy Bridge.
In our tablet benchmarks, I never saw Surface Pro break the 6 hour mark on a single charge. In most cases I’d expect to see 5 - 6 hours out of Surface Pro in light, tablet usage. Video playback was especially disappointing as Surface Pro managed to use more power here than during our web browsing battery life test. I suspect this might have to do with the relative power efficiency of Ivy Bridge's video decoder. It'll be interesting to see how Haswell does in this department.
I also put Surface Pro through some of our new notebook battery life tests for 2013, and here it didn’t fare too bad. I only have Acer’s 13-inch S7 to compare to but Microsoft managed 3.85 hours in our medium workload compared to sub-3 hours for the larger Ultrabook:
| Windows 8 Notebook Battery Tests | ||
| Battery Test | Acer Aspire S7 (13-inch) | Microsoft Surface Pro |
| AnandTech 2013 Light | 4.00 hours | 5.2 hours |
| AnandTech 2013 Medium | 2.88 hours | 3.85 hours |
This is easily the biggest disappointment with Surface Pro. You just won’t get the all day battery life you do with an ARM based tablet out of this design. I expect Microsoft will have a solution to this problem with Haswell, but not until the end of the year.
Charging
Surface Pro retains the same large, magnetic power connector as Surface RT. In fact, Surface RT’s power adapter will still charge Surface Pro. The Pro model does however come with its own 48W adapter. It’s a nice looking, but large and still fairly traditional two piece power supply (brick + detachable wall cable). There’s no sophisticated cable management other than a tiny hook to help keep the device end of the cable together. One neat feature is the power adapter does feature an integrated USB port for charging your smartphone.
Under max charging load the power supply will draw around 27W at the wall. Microsoft included a 48W unit in order to be able to charge and power the device without slowing down charge time. It took me 2.692 hours to charge Surface Pro from completely empty to 100% with no additional power draw at the wall. The quick charge time is pretty nice and about the only reprieve here when talking about Surface Pro's battery.
I did notice something odd with the first power supply Microsoft sent me. When charging through my power meter, I picked up some interference in the capacitive touch screen itself resulting in around 10% of my taps not being recognized. Microsoft supplied another power supply that seemed to resolve the issue.

Nice review Anand! It seems there is a lot of interest on this device. If you still have the unit can you please do a quick tear-down of the unit with pictures showing the cooling fans, SSD, memory, etc?Wolfpup - Thursday, February 7, 2013 - link
Fantastic review!Random thought I've had about Surface since it was unveiled...doesn't a keyboard dock like what HP includes with their Envy x2 make more sense than these touch/type covers?
I mean I get that some people use covers anyway, and leave them on (I don't on my iPad 2), and so you're sort of getting a keyboard always there for "free" for those people.
But at least judging by pictures, the touch and even type covers appear to be terrible keyboards, and look really awkward. The kickstand is nifty, I guess, but HP's Envy x2 (and some others) are basically giving you a normal notebook keyboard you plug it into, and it becomes almost indistinguishable from a notebook. That gives you a better keyboard, unlimited angles to put the screen at, and also makes it easier to sit it on your lap and type, if need be.
I haven't used either type of device yet, but from pictures it sure seems like a dock like that would be preferable to a type cover/pad?
This really is an interesting product though...I thought Apple needed to do this 4 years ago, like in place of what the iPad turned out to be, I was hoping it would be a real OS X PC running on Atom with an optional touch interface-basically exactly what Windows 8 ended up being.
I know these will get massively better even later this year with Haswell (or heck, Tegra 4), but I'm still so tempted both by Surface Pro and that Envy x2... (wish that used AMD's Z60 instead of Atom though). Hmm...an additional battery in a keyboard dock could double Surface Pro's battery life too...
And yeah, to me it seems like this ought to come with a type cover. I can understand and accept the price-this is an actual PC running hardware that runs circles around an iPad that's only marginally cheaper-but somehow it just seems like these things should be including keyboards.

"f you’re shopping for an Ultrabook today and want that tablet experience as well, Surface Pro really is the best and only choice on the market."There is at least one other device for that ultrabook/tablet experience... the Dell XPS 12. I have one on order... there are also more, like the Lenovo Yoga.

Different designs in my opinion. The Dell has the burden of always carrying around that keyboard, which means you have a 1.5kg tablet. The CPU, RAM and storage options look pretty good on that. But it lacks a digitizer which might or might not be a huge deal for you. Same thing with the Yoga. Very big (13.3"), low-ish resolution (900p), always a keyboard attatched, no active digitizer. Again, these things might be important enough to make the devices pretty much distinct categories. Or you just want "laptop-ish, touch screen, Core CPU" then they are all comparable. :DThe closest things to the Surface Pro in my mind are:
- Lenovo Helix: 11.6", 1080p, keyboard dock, active digitizer, 3G
- Samsung Ativ PC Pro: 11.6", 1080p, keyboard dock without battery, active digitizer, 3G
With the Lenovo being my dream device, because of the battery built into the keyboard dock mostly. But the dock design is fairly cool, too. :D

Almost two years ago I picked up an ASUS EP121 10 inch Tablet. It came with an i5 processor and Windows 7. I now have Windows 8 on it. Win 7 and 8 runs extremely well, as does Word, MS Project, VMWare, RDP, and all other apps I can run on Windows desktops and laptops. I.e. The Surface Pro's grand vision of a full-service Windows tablet was old news even before long it was released!Glenn Rogers

After playing around with this at the Microsoft Store today I came away feel like it was a mixed bag. I feel the build quality is really impressive and I have no qualms about the unusual nature of it's kickstand and keyboard covers. It just feels like a wonderfully solid design that takes on a more business like approach with it's VaporMg and straight line design. Honestly I just wish it came in the form factor of the Surface RT because what a difference a half pound and 3.5mm can really make. The thick form factor and weight just make it much more cumbersome to hold and I wouldn't see myself holding this thing in one for two long at all. Before anyone calls me a weight weenie you really just have to hold it in person and compare the Pro the RT before make a statement, it's a pretty significant difference. I hope the next iteration takes on a diet and comes closer to the form factor of the Surface RT because it still retains the impressive build quality without all the thickness and weight.Battery of course is another area of concern. If this thing got closer to 6-7 hours like some of the longer lasting Ultrabooks it would be a real winner IMO.
The price I feel is fine but the keyboard covers need to be included in the price. I know it's a unique design but there is no reason for MSFT to be nickel and diming here, especially in the case of the Pro. Fact is anyone looking at this device will buy either one of the Touch or Typecovers but to just spend another $120-$130 on it is excessive.
Ultimately I think this device is what most reviews say, you can see the tremendous potential and it is impressive in it's own right. It just misses on a few key things that keep it from being a product that is universally recommended as opposed to what it is right now where you need to know what you're getting into. I feel just like Anand on this, the Surface Pro 2 is simply going to be an awesome product. One that I'd buy on launch day. That being said I still might get this Surface Pro until that time comes.

Can you verify whether or not the Surface Pro has Widi support?Kornfeld - Friday, February 8, 2013 - link
WiDi is an Intel technology that requires, among other things, supported Intel WiFi adapters. Since Surface Pro uses a Marvell WiFi adapter, it cannot possibly use WiDi.The real question is whether it will support Miracast which is the larger spec being adopted by the WiFi alliance. I'm not sure if that specific adapter supports Miracast. I found this press release, but I'm not sure about the part numbers: http://www.marvell.com/company/news/pressDetail.do...
The bigger problem with Miracast right now is that there doesn't seem to be any connection software available for Windows. So, I'm sitting around with a Yoga that has a Miracast supported WiFi adapter and I have the latest Netgear device that supports WiDi and Miracast, but no application that can be used to connect to the device.

Looking at the pictures it becomes apparent that they did not pay enough attention to small details. The random 5 pin connector looks ripe for problems. And sticks out like a soar thumb.The display resolution is too low on both models. And there is no excuse for the small batteries.
It seems as if the execs at these PC companies eyes are failing them if they have not noticed these things.

Just wondering if Microsoft could have gotten better battery life by using a Core i3 or even some pentium/celeron derivative. The way i see it, the 3 main drawbacks are the price, battery life and thickness/weight of device. So, maybe using one of the aforementioned processors for the first generation product would have helped. And, they could have moved to Core i5 when Haswell started shipping.I seriously doubt that any power user could replace their notebook/desktop with a Surface pro unless you could dock it to a bigger screen and a proper keyboard. As for the regular users i don't think too many of them would even be interested in a product like this when an iPad works for them.
Anyways, i'm still going to go check it out tomorrow but most likely i'll wait for the next generation product (if it's ever released).
