Just got a Logitech VX Revolution mouse for my desk laptop. Basically, I don't have a desktop. My "desktop" is just my laptop hooked up to an external monitor, keyboard, mouse, and speakers. This new mouse utilizes 2.4ghz technology. My old Microsoft mouse had a bulky USB receiver. So this new one openned up some space on my desk making it look cleaner haha. I want to eventually go wireless for the keyboard and speakers as well.
