Because, I want to game on trips in the car and stuff.
Well you'd only be able to play single player in a car unless you get an internet plan and an adapter thingy for your laptop, get a DS and a $700 gaming tower.
True... I might as well go for a gaming tower. Since I do have a laptop I could just take with me to talk with friends and post on forums and stuff... What would a good place be to get a gaming tower? Or is it cheaper to build your own computer?
