yeah erm 1 small problem. Alot of these places don't aloow the USB ports to be used <_< also DCUO is a terrible game the servers are laggy and buggy as hell as it has no hopes of getting any better any time soon. Final point btw you have to pay to play online on DCUO, would you really pay for it each month when you don't a have a computer to play it on as/when you want ? here's my advice go buy the parts for a computer build one customly and download a game called Shin Megami Tensei: Imagine Online. It's free to play by Aria games and is awesome. It's easy to run and the comp doesn't have to be amazing.
Good Luck Ki ^.^
