iLounge has a piece worth reading called “Ten Must-Read Details on the New iPods.” Here’s an eye-opening sample:
“How much better are the new iPod screens?
Apple says that the “enhanced” 5G iPod is 60% brighter than the original, but the difference wasn’t that much more noticeable during our limited testing time. Apparently the new screens have been quietly trickled into pre-Showtime 5G iPods, and no one has noticed. Resolution of the new iPod’s screen apparently hasn’t changed from before – it still displays 320×240 resolution, despite the fact that Apple’s iTunes videos now display at 640×480 on computers. In other words, if you didn’t like the prior 5G screen, this one isn’t going to win you over, but we liked everything but the small size of the prior screen, and continue to like this new one.
“Apple’s press announcement for the iPod nano suggests that the new nano screen is also brighter than before, without quantification. We’ve seen variability in brightness in older nano screens, so it’s hard to know right now just how much better the new nano’s screen is.”
