iPad 2 to have double the resolution. 2048 x 1536 at 260 DPI.
An image has been posted by MacRumors showing some images found in the iBooks app with double the resolution (2048 x 1536) than the one currently being used on the iPad. The recent leak of specs has said that the iPad will have a retina display like upgrade. Although it’s not a true “retina display” since it’s not at the iPhone’s 326 PPI, many are saying since the iPad will be used from further away, you will not be able to see the pixels at 260 DPI.
