The iStick is designed by Alexei Mikhailov and is roughly the size of a lipstick tube, with four touchscreens. The white cube on the end does tend to ruin the look some, but it still manages to look pretty neat. It has Wi-Fi, so you can browse the iTunes Store on a screen the size of your finger.
The designer admits that the iStick isn’t for viewing movies and the screen is too small for effective photo viewing. He thinks of it more as a brother to the iPod shuffle. It’s interesting, and for some reason makes me realize that this is the way that product packaging will be headed in the future.
