The Alienware is for gaming on the go, the Asus is for gaming on my porch or for Serato when I DJ (soon going to buy a 17" Macbook Pro for Serato), the Gateway is the knock around laptop that my wife usually uses, the I7 is my main gaming machine I built, the Q9650 is my back up to my main machine that I built, the Q9550 I built for my son but I also use from time to time, the E8400 I built for my daughter that my wife uses from time to time that I also built.
I have 4 desktops (2 Dell and 2 HP) and 3 laptops (2 HP and one Lenovo ThinkPad). 1 is for home use, one is for work, one is for secret reasons, and the last is my home server. 1 laptop is my main one, one is for home use and the ThinkPad is for business.
