The Gadgeteer brings a wonderful (as always)
hands-on-review on the latest 4th generation iPod. Julie's conclusion:
People in the market for an iPod should not hesitate to buy this model, but do I recommend that 3rd generation owners rush out and upgrade? No, not unless your current device has some type of defect or you just have to have the latest model. The 2hrs additional battery life and new clicker design are nice, but for me these features aren't that compelling. As far as power, most of the time I'm near an outlet and can grab some juice when needed. I didn't have any real complaints with the old wheel design. My advice to 3rd gen owners is to just wait for the 5th gen devices. Maybe they'll have some of the cool new features that were rumored for the 4th gen.
Did she just say 5th generation iPod? Oh dear, it seems like I am always running behind time (still owing one of those of the first generation).
