the display on the iPad 2 delivers almost identical performance to the impressive iPhone 4 Retina Display. Although the iPad has a higher pixel resolution than the iPhone 4, the screen is much larger so the number of Pixels Per Inch is only 132 ppi compared to the iPhone 4 Retina Display value of 326 ppi. Lower ppi makes the pixels more apparent, an effect called pixelation. The very high ppi is a major marketing feature for the iPhone 4, but it's actually something of an overkill (and primarily there for App compatibility) because existing anti-aliasing methods can successfully reduce noticeable pixelation at lower resolutions and ppi.

Anti-aliasing is done in iOS software so Apple could (or rather should) add sub-pixel anti-aliasing to the iPad, especially given the new high-speed processing enhancements that were added to the iPad 2, and it can be done even better on the iPad than with the generic software on the Netbook. It will make a big visual improvement and take some of the unwarranted pressure off the iPad's current ppi.
