I bought a Fuze (probably like a lot of people) because I lost my iPod nano and couldn’t stomach paying a $50 premium for the Apple logo.
I’ve had a Fuze for about 6 months now…the battery life continues to amaze me. I use it almost solely for workouts and runs and charge it (honestly) rarely. I get about 5 workouts in a week and seriously charge it about twice a month. I have roughly timed it at about 20-25 hours and am also pleased that it is quite clear when the Fuze is shut off. Coming from a nano (which always seemed to be dead or just about dead), the battery life alone is enough to sell me on this player.
The only downside I can see to this player is the limited number of accessories and the proprietary charge/sync cable.
