Before I owned the iPad, one of my reasons for holding off on purchasing was to see if Apple would double the pixel density on the iPad 2. After using an iPhone 4 for a while, looking at an iPad screen looked pixelated. Over time and use, I became less interested in a Retina display showing up on the iPad 2. It's not so much because I adjusted to the current display (although I did), and it's not because of powering the display. I'm concerned about the display of content. Text would look fantastic, no doubt. But images that came from non-native sources have the potential to look horrible. Let's face it: we live in a 72-150dpi world for the most part. The iPhone 4 gets away with it because a high-density iPhone screen is still less than most desktop monitors, though if you've used an iPhone 4, you know how bad some things can look. A 2048x1536 display on an iPad would make images look poor when browsing the web. iTunes artwork at its current dimensions would suffer. Images pulled into apps from outside sources (Twitter, RSS readers, etc.) are bound to appear pixelated. Until desktop pixel density starts to catch up, I'm really wondering if the experience of those activities (particularly web browsing) would suffer on a Retina display. That said, knowing Apple, they wouldn't do it if the experience suffered that much. Thoughts?
