Having owned several music players in my time the iPod is by far the easiest to use. Finding what you want is a doddle, and it is high quality all round. Don't believe the reviews from those who say it sounds crap compared to the iPod video; it really doesn't and if you can use some Sony earphones as they are better than the supplied Apple ones.
Biggest thing for me is battery life; ran my battery flat (almost) last week; it ran for over 34 hours with me skipping tracks and even watching some video towards the end, but I didn't get to run it completely flat as I wanted it fully charged for the morning. It was getting very late and I just couldn't drain it as the power consumption is so good. The battery indicator was still in the green after 30 hours too.
It certainly exceeds the 30 hours music time Apple specifies and I reckon it will do more than 5 hours video. Great value for the amount of disc space you get.
