The Logitech MX Air mouse is a regular laser mouse that also operates in three dimensions. Using similar technology to that found in the Nintendo Wii controller, the mouse uses 'Freespace' motion sensing technology to translate hand motions into cursor controls.
Distributor Ingram Micro is offering one of these - worth £99.99 - to the lucky winner of this month's PC Retail competition. To be in with a chance of winning, just answer this question:
