Achieving Retina
To make the MacBook Pro’s Retina Display a reality Apple had to work with panel vendors to build the panels it wanted at a reasonable cost, as well as deliver the software necessary to support insanely high resolutions. There was another problem Apple faced in making the rMBP a reality: the display pipeline of the GPUs Apple wanted to use didn't officially support scaling to the resolution Apple demanded of them. Let me explain.
All modern GPUs have fixed function scaling hardware that is used to efficiently scale between resolutions. A scaler either in your GPU or in your display panel is what lets you run non-native resolutions at full screen on your LCD (e.g. running 1680 x 1050 on a 1920 x 1080 panel). None of the GPUs used in the Retina Display MacBook Pro officially support fixed-function scaling of 3840 x 2400 or 3360 x 2100 to 2880 x 1800 however. Modern day GPUs are tested against 2560 x 1440 and 2560 x 1600, but not this particular 5MP resolution. Even 4K resolution support isn’t widespread among what’s available today. Rather than wait for updated hardware and/or validation, Apple took matters into its own hands and built its own GPU accelerated scaling routines for these higher resolutions. Fixed function hardware is almost always more efficient from a performance and power standpoint, which is why there’s some additional performance loss in these scaled resolution modes.
What’s even crazier is Apple wasn’t pleased with the difference in baseline filtering quality between the Intel HD 4000 and NVIDIA GeForce GT 650M GPUs. As the Retina Display MacBook Pro would have to regularly switch between GPUs, Apple wanted to ensure a consistently good experience regardless of which GPU was active. There are a lot of filtering operations at work when doing all of this resolution scaling, so rather than compromise user experience Apple simply wrote its own default filtering routines. Since you want your upscale and downscale quality to be identical, Apple had to roll its own implementation on both. Apple’s obsessive attention to detail really made it possible to pull all of this off. It’s just insane to think about.

No one said it was quad, this is in 2010. Arrandale had higher thermals, and today's version does have quad.OCedHrt - Sunday, June 24, 2012 - link
Not quad core. Quad raid. As in, 4 separate custom SSD boards connected to 4 separate SATA ports in raid 0. This was before there was 500mb/s raid from SF. Now it's kinda a marketing gimmick because they're not 4 500 mb/s raid that gives you nearly 2 gb/s in raid 0.Totally - Tuesday, June 26, 2012 - link

"...fastest of the dual core i7's while..."
no one mentions anything about a quad core cpu

I looked up the current model. Vaio Z: 13 inch display 1920 by 1080, maximum 8 gigs ram, 512 ssd, quad core i7 2.1/3.1 , USB 3. However, no thunderbolt, only integrated graphics and the price for the 13 inch computer as above is $2999.Does not compare to the retina macbook pro which has a higher resolution 15 inch display, thunderbolt, significantly faster processor, and discrete graphics with a gig of vram. The price for the better retina macbook pro with the 512 gig flash drive is $2799.
There is no comparison.

The Sony you linked to doesn't have discrete graphics. You have to buy (and use) the docking station to get that.If you load it up with 8 GB of RAM (which is the max, while the rMBP goes to 16 GB), a 256 GB SSD, a 10% slower CPU (2.1 versus 2.3 GHz), no discrete graphics, and a "HD" non-IPS display, it costs you $1,950 versus the rMPB's $2,200.
For the price Sony charges for the upgrade to 512 GB of SSD ($600), you can upgrade the rMBP, to a 512 GB SSD and get a 20% faster (2.6 GHz) CPU thrown in as well.
The non-IPS display means that even if the rMBP didn't have incredibly more pixels, it would still outclass the Sony display in terms of contrast, viewing angle, etc.
The Sony weights about half of what the rMBP does, but it also has less battery life and it's about the same size. I guess the VGA and ethernet ports are a big deal for you, though of course you don't get two Thunderbolt ports. Oh yeah, you also get a Sony MemoryStick slot, too!

http://www.anandtech.com/show/5430/sony-vaio-z-wit...It is an IPS display, but non-glossy.
Don't bother comparing the 2 as apples to apples, because they're not comparable. The sony is 2.5 lbs versus 4.5 lbs for the macbook pro retina. You have a whole different power and heat envelope.
I don't disagree that Sony is overcharging for the high end Z, and now with the retina macbook pro maybe they will lower prices (this is really the first contender, but it is 15" so targets a different market segment).
However, you can get the last season's models on the Sony outlet store for 40% off - ie $1400 nets you 256 GB SSD, 8 GB of ram, the external dock with graphics and blu-ray, etc.

Z has never had IPS, it's SE series. Still nice laptop though.OCedHrt - Monday, June 25, 2012 - link
I stand corrected, but it is still way better than a TN and not much worse than an IPS (you lose out on viewing angles).Spunjji - Monday, June 25, 2012 - link
You're missing the point of why this product was brought up. But hey, good effort for not reading the preceding posts.cptcolo - Tuesday, October 23, 2012 - link
Wow that Sony VAIO Z Series is impressive!Personally the laptop I am holding out for is something along the lines of:
17" 2560 x 1440 (or 2560 x 1600) Matte IPS Screen
Broadwell Hex-Core, <25W TDP
Super Integrated Graphics (no graphics card or optical drive)
32GB RAM on 2 DIMMS
x2 512GB uSSDs in RAID0 over 16Gb/s interface
100+ WHr Battery
Overall size less than a typical 15" via a thin bezel.
Weight: <4.8lbs
Thickness: <0.8"
Excellent Keyboard/Trackpad and great build quality.
All for ~$2500
