the shuffle is super tiny compared to all the harddrive based players. if you're looking for a casual listening device, the shuffle might be a good choice. if you want a portable library, then look at a hard drive player.
DAP review just did a fairly balanced review of the shuffle (in my opinion)

the shuffle's sound quality, size, and price are its key features. its a great barebones player, and itunes is pretty good for keeping your music library in order and creating playlists for the shuffle.
almost all mp3 players act as plug and play hard drives (no drivers). the shuffle one-ups them buy having a USB thumb drive form factor with a built in plug. with others, you will need a cable. but, obviously with a hard drive player, you could store more than with a flash player.
if you're looking to add/transfer music that you also want to listen to on the player, then the ipods require a bit more work than other players. the shuffle is designed to only sync musically with one computer. you can move files around however you want, but if you want to put on music that you want to listen to, you can only use the original computer, otherwise you are asked to format it and start fresh.
edit: plaqued with problems??? like what? are you sure its not just user error? and what percentage have been considered defective? you may have recieved a good number of returns, but that does not mean they are truely defective, nor does it mean they are "plagued". you could have just sold a whole crap load.
