"Good for it's size - so-so for it's money"4.0 starson by wazo502
Pros: it's so small and so cool, color screen, no skipping (flash memory)
Cons: black is very easy to scratch, for $50 more, you can get the iPod video 30GB, it's only 4GB
Summary: I got the 4GB Nano as a gift -- the first thing I liked about it is that it's so tiny! If you have USB 2.0, the songs loads pretty quickly, at least it did for me. The screen is pretty cool as it's a color screen. It supports Photos (although you have to load this from iPhoto ... not sure how that's going to work on the PC side). The sound quality is pretty good, even with the default Apple ear buds. battery wise, I don't know how other people compared battery life to say that it's bad, the rate that I was recharging te battery seems okay to me. I listen on average of 1 - 2 hrs per day; sometimes more, sometimes less. My recharge rate has been between 1 week to 2 weeks, depending on usage.
Now, the downside: the Nano is easily scratchable! Mine got pretty scratched up within 1 week of use. If you care about the appearance of your Nano, I would get a protective cover for it ASAP. The other thing about the Nano is the price. At $250, I can pay $50 more for a 30GB iPod Video! If you like to put all your CD collection on your iPod, the Nano won't do it unless you have a pretty limited collection or don't want every music you own to be on the Nano. When I first got the Nano 4GB, I thought ... wow! 4GB of space! Boy, how quickly I can fill that thing with my CD collection!
If it's size and coolness you want, iPod Nano is definitely COOL! If you can shell out $50 more and want the extra space + don't mind the size of the iPod Video 30GB, then go for that instead.
