Ideal to control a HTPC if you don't want a full size keyboard and mouse hanging around & cheapest I can find it.
Enjoy total control of your PC entertainment from your sofa. Palm-sized, cordless mini-keyboard fits in your hand and optimises access and control of the PC entertainment you love. Integrated dual-purpose ClickPad works as a touch pad and a directional pad. Rechargeable Li-ion batteries included. Bluetooth wireless technology provides long-range control from up to 10 m
Don't really see the point in listing all the tech spec on here as it's on the amazon website anyway.
Hope the link & image works - I've only posted a couple of deals before!
