Replying to Ipod advice

I have an ipod mini, the 4 gig and its way too small to hold anything. and itunes pisses me off on so many different levels.  I was wondering if its worth it to:

a) Go for a different mp3
b) Sell it, and go for a bigger one
c) how do you change it so you can still plug in to other peoples computers and not have it erase your stuff?

Any ideas would be awesome.  Thanks

Oh yeah, and i figured i'd just put it out therethat skiing in rain sucks so much. Eastern PA got about 2 inches last night, and i was skiing in puddles.  no good
