It has long been rumored that the new iPad 3, expected to be announced March 7, will come with a 2048 x 1536 retina display — an amazingly high resolution. Now MacRumors has has obtained one of the displays to be used in the iPad 3 and, based on close analysis, has deemed that in fact it is a retina display. Since they weren't able to power up the display, not having the iPad itself, they resorted to using a microscope to compare the pixel density of the new display with that of the iPad 2. Very resourceful.
