picked up one of these earlier and its a great wireless desktop set up,just plug in the usb dongle and press connect and thats it,they supply a usb lead but not required just plug straight in the comp as the range is excellent and keeps your desk completely wire and connector free.
not the cheapest but quality and worth paying a bit more for,pc world have it priced at £74.99 instore so the assistant was shocked at what i paid lol.
even comes with a handy plastic cover:)
£43 at amazon with some good reviews and more expensive elsewherehttp://www.amazon.co.uk/Logitech-Cordless-Desktop-Wave-Mouse/dp/B0009HJDIY
