I'm still in the market for an MP3 player. At the time I got my 4 GB Muvo^2 it was way more than I needed. Now amazingly I have 12 GB of music on my hard drive. So I have to pick and choose what I take out with me, which sucks. Sometimes I want loud angry music, sometimes I want soft relaxing music, sometimes (like at work) I need something in foreign language so it doesn't distract me.
I'm looking forward to the next generation of iPods being released. Because it will probably drive the price of all the non-iPods down enough that I can finally buy a new one. I had the misfortune of having to use my sister's iPod for a while recently, and I can't see what the fuss is about. Certainly not worth the price tag nowadays. Certainly not worth whatever price tag they put on it if/when they replace all the buttons with a pointless touch screen.
But everything else on the market right now doesn't look that great either. Either lacking in features, or too expensive. anythingbutipod.com is a pretty good site for posting news about non-iPod MP3 players, which is nice. But I don't even see any pending soon-to-come MP3 players that I care much for. It seems like the majority of the market is aimed toward cheap flash-based tiny MP3 players for non-geeks.
All I want out of life is a ~60GB MP3 player with a small color screen that maybe displays album art but doesn't necessarily play movies, with good battery life and most importantly a little door that lets me take out the battery and replace it, with no silly Windows WMA dependencies or massive DRM crippleage, for a reasonable price. Create such a device and I will purchase it.
