iPod Touch Tube- The iStick is the size of lipstick tube. But it has four touchscreens for four times the Coverflow. I don't really get the white cube eating up a quarter of the stick though—why not just make the whole thing a solid tube of touchscreen, with the bottom and top holding the single button and earphone jack?

It also has Wi-Fi, for browsing the iTunes Store.
