Microsoft Surface Review

Display: Not Retina, But Still Good
Surface features a 10.6 inch, 1366 x 768 16:9 display. The physical size is a bit unusual, although the display resolution is something we’ve seen used in affordable notebooks for years now. We already know why Microsoft picked the display size (to enable better multitasking and make for a good keyboard size), but is there room for a flagship tablet with only a 1366 x 768 display resolution?
Microsoft’s response to the resolution question is that more pixels isn’t necessarily better, and that there are a number of other factors that are just as important. It also is quick to point out that a significantly higher resolution display would have increased memory bandwidth requirements, decreased UI frame rate and required a larger battery. As NVIDIA’s Tegra 3 only has a single channel LPDDR2 memory interface, driving a 2048 x 1536 panel and maintaining Microsoft’s UI performance requirements was out of the question. Apple ran into the same issue and ended up building the A5X SoC with an insanely wide memory interface to deal with it. Down the road I’d expect the memory bandwidth problem to get solved, but that still leaves a power consumption issue. Apple moved to a 42.5Wh battery in the 3rd generation iPad, a 37% capacity increase compared to the 31Wh unit in Surface. Enabling a similar panel would have pushed size and weight of Surface more than Microsoft would have liked.
Given those constraints Microsoft chose a different route with Surface. Rather than focus on pixel density it focused on improving contrast and reducing glare. Surface laminates the cover glass and LCD panel together, removing an annoying air gap that’s responsible for some reflections/glare and a reduction in brightness. Apple’s recently announced 8th generation iMac does something similar, as do a lot of high end smartphones, but Surface is among the first to do so with a ~10-inch LCD. The effect is noticeable in a contrived photo but it also results in a display that’s not half bad to look at.
With the exception of text on web pages, the lower resolution Surface display isn’t overly bothersome. I would like something a bit higher resolution although I don’t know that matching Apple’s pixel density is absolutely necessary if Microsoft can deliver elsewhere.
Apple doesn’t just rely on resolution to sell the iPad’s Retina Display, it also happens to do quite well at accurately representing colors. I put Surface through AnandTech Senior Display Editor, Chris Heinonen’s excellent tablet/smartphone analysis workflow to see how well it did:
| CalMAN Display Comparison | ||||||
| Apple iPad (3rd gen) | Apple iPad 2 | ASUS Transformer Pad Infinity | Microsoft Surface | |||
| Grayscale 200 nits Avg dE2000 | 3.7333 | 1.3826 | 3.9881 | 3.6769 | ||
| CCT Avg (K) | 6857K | 6632K | 6632K | 6407K | ||
| Saturation Sweep Avg dE2000 | 3.193 | 6.8404 | 6.8404 | 7.3617 | ||

Grayscale accuracy is slightly better on Surface compared to the iPad, however the rest of the accuracy metrics show Apple’s tablet ahead of Surface.
This isn’t to say that Surface’s display is bad, in fact I think it’s quite good and I’d argue that it was never a problem in my testing, but it’s definitely not the best on the market today. I’m also not sure how much of this has to do with Microsoft’s panel selection vs. software calibration. None of my calibration tools work under Windows RT so I couldn’t really tell you.
I did reach out to Microsoft and they did say that some of my values in the charts below looked a little off. I’ll be rerunning data on another Surface sample as soon as I get a chance to.

I am right now typing on my lap using the $599 3.4lb Visio Ultrabook with 1600x900 14'' real IPS screen, iCore 3 Ivy Bridge CPU with HD4000 graphics, 128Gb SSD and 4GB of RAM that can run both MS Office, Photoshop and Bioshock with the supreme authority and multi-task like there is no tomorrow.This incidentally is the exact same price that Microsoft wants for Surface with touch keyboard.
To me, IMHO, after you remove all that magnesium this and kickstand that marketing slogans taken straight from Microsoft brochure, my Visio Ultrabook is a much better and more important, usable device, period.

Cool story bro. Wish you weren't lying about the IPS screen thing.karasaj - Wednesday, October 24, 2012 - link
Does anybody think that an S4 Pro update or Tegra 4 in January-February of 2013 for Surface RT at the same price point as the current surface would be possible? That would be a serious tablet I think. It seems like Surface needs just a little more oomph to be a fantastic piece of equipment - how likely do y'all think (Anand reply maybe?) this is possible?Krysto - Wednesday, October 24, 2012 - link
If Tegra 3 wasn't enough. S4 Pro won't be either. And you won't see a Tegra 4 Windows device until next fall.What Anand masterfully avoided to say in his review (who knows why?!) is that Tegra 3 works a lot better with Jelly Bean than it does with Windows RT. Windows RT just doesn't work as well as Android or iOS on the weaker ARM chips, and it needs something a lot more powerful and more expensive to run adequately. I mean it needs 2-5x the time to open an app compared to iPad? Really?

Well S4 Pro is a good bit stronger than Tegra 3 especially in single threaded stuff, no? We've seen it match up to the iphone 5 already, while Tegra gets beat bad.kyuu - Thursday, October 25, 2012 - link
Don't listen to Krysto or Netscorer, they don't have anything useful to say.I agree, the Tegra3 is obviously about the minimum WinRT can get away with. I'm not sure why MSFT didn't go with an S4 Pro or just plain S4 clocked up a bit. They're already using Qualcomm SoCs in their Windows 8 Phones, and either way (particularly the S4 Pro) would've been better than the Tegra3.

Honest review(this and the other RT device) and certainly more in-depth than CNet, Gizmodo(2 stars) and the Verge, that managed in one page to destroy winRT/AsusVivo.Krysto - Wednesday, October 24, 2012 - link
Honest review because you like it? I think Anand tried to make it as good as possible with all its negatives. That's not objective, that's covering up its flaws, in a biased manner.kyuu - Thursday, October 25, 2012 - link
Yeah, couldn't be that you're picking on the negatives and dismissing the positives because you're the one who's biased.Nah, couldn't be that.

When does the surface pro get released?If I can install all my work software under standard windows on a tablet of this quality I'm thinking I might be ready to bite. This would be so much more convenient to work on a plane with or in bed at night then my laptop. (Plus I can actually be productive instead of play games on my wife's iPad lol)
