"decent for the light user; research more if you want to use it a lot"2.5 starson by iconform
Pros: pretty, easy to navigate, fairly small for its capacity in its time
Cons: short battery life, not very durable
Summary: They say it has a long battery life - it doesn't. After a few months, mine was lucky if it could last my going to class, going between classes, maybe an hour or two in lab, and returning from class.
I dropped mine twice from pretty low elevations - it seemed OK at first. A few months later, it started skipping, then it'd work sometimes and not othertimes, and then it just utterly stopped working. To this day, I'm not sure if the dropping it killed it or if it was just always going to die like that - it hadn't even been a year. Apple declared that the damage was not covered under the warrantly, and now I have quite a pretty, expensive paperweight.
Still, if you're lucky and very careful with your's, and not very obsessive about getting your playlists just so, the mini's easy update and use. Plus, it makes a great gift. If you want quality though, I suggest checking out some other brands - I later replaced my iPod with a Creative Zen, and love it a lot more than the iPod.
