check the c|net reviews. I think you are referring to the Gigabeat S? Both are good but getting old though. The Gigabeat was smaller and thinner, the screen was .1" shorter but still the same colors and resolution. It's harder to find than the Vision M, and Microsoft crapped out the hardware for the Zune
I am looking for pros/cons for each of these. I am undecided between the 30GB and the 60GB. It is important that it is easy to use, user replaceable battery, good battery life, drag and drop interface to pc, and FM tuner. Also, needs to have at least generic accessories such as cable to connect to home stereo, car, and remote speakers. THX!
