"It's no small secret that the next iPod will feature a touch sensitive screen. Save perhaps an on/off switch, there may be no buttons or dials at all on the device. The entire front of the machine should be all screen, making it look more like a pocket-sized plasma TV than a current generation iPod. With the recent Nano scratched-screen debacle, I hope Apple includes a cover for the screen. An ideal design would be a clamshell cover that perhaps folds all the way around to snap into the back of the unit. The now famous click wheel is believed to appear on the screen when you touch it, maintaining the same functionality which is as elegant as it is genius."
