Both tablets will include a 10.6-inch HD display with Microsoft's "ClearType" sub-pixel rendering technology behind Gorilla Glass 2.0 from Corning. According to Michael Angiulo, Microsoft's corporate VP of Windows planning, hardware and PC ecosystem, technology in the custom-made display "makes it impossible for the human eye to distinguish individual pixels when held at the optimal distance of 17 inches, less than an arm's length."
Apple makes similar claims about the 9.7-inch Retina display, which it unveiled in a 2011 iPhone, added to the iPad 3 and now offers on its Macs too. Apple says that at 264 pixels per inch, Retina's pixel density closely matches that of the human retina and doubles that of the iPad 2. Microsoft wasn't specific about the maximum pixel resolution of Surface for Windows RT, but since it claims a 16:9 HD display, we have to assume it's at least 1,920 x 1,050. Since the iPad 3's specified resolution is 2,048 x 1,536, we'd give this one to Apple.
