FaceTime HD Cameras
One of the more subtle changes between the 2010 and 2011 MBPs (and other MacBooks) is the departure from strictly VGA "iSight" cameras. The new FaceTime HD cameras are 1280x720, though Photo Booth oddly still only captures at just VGA.
A quick run to the command line and use of isightcapture enables true native resolution capture at 1280x720 until Photo Booth gets updated (if ever). I propped a 2011, 2010, and 2006 MBP up inside my lightbox and setup the scene I usually use for smartphones, and tossed in a GMB color checker card. I took photos from the command line at full resolution with no compression with both tons of light from a huge CCFL, and again with very little light. You can immediately see how things have changed if you check out the gallery with those uncompressed photos at native resolution.
The 2011 MBP's optical system achieves almost the exact same magnification (eg the height of the test objects remains the same if you scale vertical resolution) as the 2010 model. You just get a wider image at higher resolution. It isn't perfect, and even with gobs of light there's noise visible, but the quality is dramatically better. White balance is changed, with the old 2010 model having a slightly reddish cast. The difference is easily discernible in the color checker card. The old model also had less than perfect exposure (the light part at the right of the cup is completely saturated) compared to the new. Dark performance is also slightly better, again with a different color cast.
Visually, I was hard pressed to notice anything different between the two cameras on the outside. The older 2010 MBP seems to have a larger aperture, subjectively, which seems the opposite of how I'd expect things to go.

The other part of the story is of course FaceTime HD itself, which ups the quality of FaceTime sent from the 2011 MBP from 320x240 to 720P. While the new MacBook Pros ship with FaceTime preinstalled, older Macs need to purchase it from the App Store for $0.99. FaceTime HD leverages Sandy Bridge's Quick Sync for encoding 720P, although as we pointed out earlier—CPU utilization is still quite high. While only 2011 MBPs can send HD FaceTime, there are also restrictions on what Macs have enough processing power to decode it.
FaceTime HD works pretty well. The application starts in a small portrait window but is both scalable and viewable in landscape as well.
There's no support for text communication during a FaceTime HD chat, just video. The video quality scales dynamically with available bandwidth. FaceTime HD worked over a 512Kbps upstream connection but had reduced quality compared to transmitting over a 2Mbps connection.

Our top picks right now are either the Intel SSD 510 or something based on the SF-1200 controller (e.g. Corsair Force, OCZ Vertex 2). In the next month or so we should see the first wave of SF-2200 drives hit the market (e.g. OCZ Vertex 3). These things should scream. Keep an eye on our Storage section for new drives as we review them:http://www.anandtech.com/tag/storage
Take care,

I purchased the low-end 13" the day it was released, and am super happy with it. I had been waiting for a while for a suitable upgrade to my 2007 White Macbook. I considered getting the last 15" (almost bought it), but I was worried about heat, size, and weight. Turns out that these concerns were justified, but the Sandy Bridge models seem to be much better.The performance of the new 13" is comparable to the old high-end 15". It is noticeably faster than the last-gen 13" (I have one of those at work). I don't really play games on my laptop, so I don't care about graphics (I have a desktop with a GTX460 at home hooked up to my HDTV).
I have played with all of the other laptops, and the build quality on the Macbook is just better than anything else I've seen. No question about it. Every time someone raves about some other laptop, I go to Best Buy and play with it, and I'm always disappointed (usually the keyboard and/or trackpad sucks, or the case is too flexy).
Sure, I could get a faster laptop for less money, but it wouldn't be as good at what i actually use it for (mostly software development). I got the low-end 13", and will use the money I saved to buy an Optibay and 128GB SSD (already upgraded the RAM to 8GB). The only laptop that could potentially beat it is the forthcoming MBA.

ah except for when i bought it this is how it's gone for me too. and except for waiting to max memory if usage needs it. and maybe hoping for a slicker hybrid hard drive solution, something like the momentus xt but with more cache and a variable spindle.i wonder if the i5 model runs cooler than the i7. we stressed it with handbrake, experienced the fan, felt the underside. it didn't seem to get intolerably hot underneath unless there was zero airflow (like, on a bedcover).
oh btw here is a document of the hidden keyboard secrets of the fn key.

oops error. the return of the hidden keypad was actually done by a software extension w/o my knowing. pretty thrilling to report that though, while it lasted.kanaka - Thursday, March 10, 2011 - link
I got my 15" AG yesterday and one of the first things i was impressed with was how sturdier the hing was compared to my existing Late 08 model.owbert - Thursday, March 10, 2011 - link
what is the trade offs between high res antiglare option and high (glossy) res display?kanaka - Thursday, March 10, 2011 - link
Glare vs no glare. Also colours are more saturated on the glossy screen. There's also a slight weight difference due to the glass vs no glass situation.mino - Thursday, March 10, 2011 - link

More brightness and color saturation on the glossy screen, but more money better color accuracy, reduced glare, and slightly lower wright on the matte screen. The matte screen is also higher resolution than the standard screen, but you can get the hires screen in glossy or matte.One side benefit of the matte screen, in environments where glare may be a problem on the glossy screen (e.g. The Apple Store, many offices, etc), I find it's necessary to turn up the screen brightness on the glossy to overpower the glare. With the matte screen, I can use a lower screen brightness, which means less power, and better battery life. I'm not sure how much difference since I don't have a MBP with a glossy screen to perform a side by side test, but I estimate it at 15-30 mins.

The new Sony S is better.
