Default scaling will inevitably have a hit in performance.
Apparently not even at the native retina res there is no scaling:
http://www.anandtech.com/show/5996/how-the-retina-display-macbook-pro-handles-scaling

Apple offers five scaled settings including the default pixel doubled option: 1024 x 640, 1280 x 800, 1440 x 900, 1680 x 1050 and 1920 x 1200. Selecting any of these options gives you the effective desktop resolution of the setting, but Apple actually renders the screen at a higher resolution and scales it to fit the 2880 x 1800 panel. As a result of the upscaled rendering, there can be a performance and quality impact. It's also worth noting there's no default option for 2880 x 1800, which is understandable given just how tiny text would be at that resolution. I suspect it won't be long before users figure out how to manually add a zero-scale, 2880 x 1800 option.

Evan, unless an application has been re-written for the retina display it will use pixel-doubling to look the same as on a non-retina display.

  I have and indeed it does look absolutely fantastic, and I'm all for new high res screens, especially to emulate printed material.
 But there first must be a major overhaul in all OS & apps to be resolution independent.
 In the current state of things ultra high res in small displays just makes it hard to use for productivity, with menus & text being too small & hard to read.

If you have used the new iPad you'd know that comment doesn't hold water. It's even more pixels, in higher density, on an even smaller screen and it looks absolutely fantastic

Using Kepler nvidia GT 650M for the macbook yet keeping 2 year old Ati's for the macpro???
 
 As for the retina display, at last IPS on a macbook pro, but $400 overhead to the non retina version is a 24" IPS monitor itself..
 And as Stephen mentioned al these pixels are great but crammed in 15 inches won't be very productive.
 I had a 15" Dell Precision 1920x1200 once and I needed a magnifying glass or glue to the screen to see what was going on ...
 There is no option for antiglare for the retina model, just a note in the features that it is antiglare?

Same graphic card? :S
 
 I hoped there will be at least a smaller quadro card or other Nvidia...
 
 Maybe I don't find the important information on the site but no USB3? Thunderbolt?
 
 I guess the next hardware announcement will be an iMac like the Z1 and after that they will kill the MacPro.

 I�m not sure if it�s awesome or not. That many pixels on a 15� screen? Even with OS and app support, it may be just amount to really expensive text smoothing. Other than text, I�ve not seen really compelling usage models with Retina screens in phones and tabs for photo and video. The rest of the updates are not any different the myriad other notebook announcements of late.
 
 Have to admit, even though I only Hackintosh as my primary boxes are Win, I�m a surprised at no new Mac Pro. I mean, I can understand not a whole new case etc. but dropping in updated motherboard, PSU, CPUs, video, USB3 etc. would not have been a very big effort for Apple. That�s not a great sign as later summer and fall announcements for Apple are probably iPhone related for holiday season.
 
 
 I wonder if there is not some serious internal debate about this since Ars Technica and other sites claimed to have insider info on new Mac Pros.

 Love the resolution of that display. Pixels galore!
 
 No word on the Mac Pro's huh?

 looks amazing. retina display, ssd hard drive, quad core i7 and a kepler 650 GT, with 7 hours of battery life. I'm not much of an Apple guy for workstations but I do think they make the best laptops in the industry. Glad I waited to update my 2010 mbp. Also glad they decided to switch back to nVidia graphics.
