Hi I just bought my new iMac 27 inch just before the new thin one came out and I'm just wondering can you use a wireless keyboard and mouse that uses a receiver which you plug in to a USB port to setup windows 7 because I've been told you can't use your apple keyboard or mouse and the only thing I got around the house is a keyboard and mouse which uses a receiver which you plug into your computer/iMac via USB. 1 micro receiver for the mouse and a another receiver for the keyboard. Thanks guys! Also. Is the installation a smooth one?
