We saw some fascinating cell phone innovations from Motorola at CES. First was the ROKR E8 phone, with its Modeshift technology. The phone doesn’t have keys. Instead, when turned on, “virtual” keys appear. When pressed you actually feel a vibration, confirming you‘ve pressed the button with a bit of tactile feedback. When you switch the mode to music player, all the cell phone keys vanish and a whole new set of buttons appear, specifically for the player.

Very impressive. Pricing and carriers are not yet available.
