Ok, so I ordered a new iMac (waiting paitiently...) to replace my old one. I went with the wireless keyboard and mouse option to get rid of the wireless clutter. I bought a MX Revolution about 6 months ago. What do you guys think? Should I keep my MX Revolution and just keep the Mighy Mouse in its box until I decide to sell the computer and upgrade again or make a few bucks on ebay and sell my Revolution?
