Well the name says it. I hate having to go to another part of the room just to play a video game I don't have on the PC. I think that the PC should have a big case to fit the Xbox inside there also.
Ben really dislikes combo systems, especially one using soon to be last gen such as the 360. Why can't you just put your 360 next to your PC and hook it up to the same monitor? Or get a video capture card?
