Rumors surrounding the iPad 2 have been swirling for some time now. The latest rumors indicate the next iPad model will sport a higher resolution screen. The current iPad has a resolution of 1024x768 and 132 ppi. There has been much talk lately that Apple will be including a Retina Display (300 ppi) with the next iPad, but that is highly unlikely. A 9.7-inch screen with a resolution that high would be impractical. It’s far more likely that Apple will simply double the horizontal and vertical resolution as they did with the iPhone 4. The iPhone 3GS has a resolution of 480x320, while the iPhone 4’s screen was increased to 960x640.
Recently, a developer found artwork within version 1.1 of Apple’s iBooks app that was larger than typical iPad images. Upon closer inspection the image seemed to be pixel-doubled.
