MacRumors has a very interesting look at the new MacBook Pro Retina display and some features I didn’t know about. It seems you can increase the apparent resolution of the 15 inch display by decreasing the PPI. Normally the display is equivelent of a 1440 x 900 display at full PPI, but cna be changed to 1680 x 1050 High-Res or 1920 x 1200 and you just lose pixel density, but would be awesome for editing.
Also the loss of the glass cover is supposed to reduce glare by 75%!
Of course it is now coming out that it has no user upgradeable parts and soldered RAM, so buy it with the Max RAM that you will need because you won’t be adding anymore later!
