Or for another $90 or so, you can get one of these
Amazon.com: Toshiba MES30VW Gigabeat 30 GB Portable Media Player (White): Electronics
I know it is a bit more, but ****, i got one and they are brilliant. So easy to use, great interface and screen, plays video, radio, lots of diff sound file types, pics, and also if you record tv you can automatically stream it through onto that so you can watch later.
Also with 4gb or 2gb you are going to run out of space for your music pretty **** quickly imo, unless you dont listen to much. And if you dont listen to much, get a vinyl player imo =P
****, if you do listen to a lot of music, get a vinyl player, ahha
