It should also be noted that while the screen is physically slightly bigger than the iPod's, it contains the exact same number of pixels. So you're not getting any extra screen real estate, and you also get the added benefit of having most of your videos stretched out of proportion.It's the size not the resolution that is important because the video content isn't able to take advantage of any higher resolution. If what you said is true, people would watch standard (not HD) TV on iPod-sized devices. Go Apple Fanboys!
Actually, the iTunes store sells their video at 640x480. They claim it's so that it will look better when you pipe your videos from your iPod to a TV, but most people believe they're just planning ahead for the 6G iPod. My original comment stands: The Zune's screen, while slightly bigger, is no better, and will just stretch many videos out of their aspect ratio.
Go Apple Fanboys? Well, if that's how you wish to define "the entire consumer base of planet Earth," be my guest.
Uh, at the distances you watch either the Zune's or the iPod's screens, the slightly smaller screen on the iPod would look the same size as the Zune's simply by holding it about 1 inch closer to your eyes. These are not large screen HD TVs, you know.
