Are you happy with the battery life on the Fuze?

I’m slightly disappointed with my battery life.  It’s a couple of years old, so it’s a reasonable 8 or so hours.  It lasts me a few days, since I’m not a hardcore user.

I wouldn’t mind thickness at all.  The brick of an iPod Photo feels good in my hands, but a more reasonable thickness would be a Fuze sized player with the thickness of an e200 (with a replaceable battery, of course).
