Photos: Motorola's sexy new Rokr E8 and Z10

Turned off and the E8's glossy black casing reveals little about its features. Turn it on and the flat keypad and colour screen light up to reveal a futuristic phone that combines vibrating feedback, a touch-sensitive scroll wheel and a new interface.

There's 2GB of onboard memory with the option to add more via a microSD card slot, a standard 3.5mm jack at the top so you can plug in normal headphones and stereo Bluetooth if you prefer to go wireless.

We were impressed by the vibrating feedback that works when you touch the flat keys and really makes you feel that you've touched a mechanical key. The E8 vibrates just under your thumb rather than the whole handset.
