Here is an interesting design concept, which would definitely rival the new iPod Shuffle, the iStick.

The iStick features a touchscreen interface on every side of the device, it also features a silver cube at the end which is used as a scroll wheel, to navigate through your favourite tunes.

It certainly looks like a great design, but I expect it will be a while yet before we see Apple producing an iPod like this.
