I got my Dell DJ over the weekend. I have a few friends that own ipods and I decided to try something different and it being about $100 cheaper doesn't hurt. So far the differences between the two players are very minuscule. Transferring my 10gigs of mp3s to the player took a few hours since I only have USB 1.1 (I'm thinking about picking up a USB 2.0 card soon).

Overall I'm very satisfied with my choice to go with the Dell DJ and the addition of a fm transmitter makes it really nice when listening to it in my car or through my living room stereo system.
