We don't have an ipod. My wife has about 10gigs of mp3 files, and I thought of buying her an mp3 clock radio for Christmas, something with an SD card or USB port to plug in a thumb drive.
On amazon, everything is geared up for ipods, especially ipod touch and the iphone. I did manage to find one clock radio, a Timex that took SD and USB sticks, but it was discontinued.
Surely it is cheap enough to incorporate an SD card slot and update the firmware to play mp3s on a cheap clock radio, or even a high-end audio dock.
