Well, I decided to go with the iRiver 890t 256mb player. One thing, it's not gonna be at retail until the end of the month. So, I bought the previous model of it, the 390t, which is basically the same except for exterior design, has usb1.0 instead of 2.0 on the 890, and only gets 24hrs per battery compared to 40 on the 890. I'm going to exchange for the new model when it comes out. They both use the iRiver software to transfer files back and forth to the computer. USB 1.0 is slow, can't wait for the new model to come out. Radio reception is good and strong, up to 20 presets. You can organize your mp3s via folders (not sure about playlists yet) or put them in the root directory. You place them in the order you want them to be on the player. There are multiple shuffle and repeat selections. It sounds good with the included earbud headphones, lacking bass...gonna need to pick up some higher quality ones. I'll let you know how I like it after some use.
