I would rather have a console I can spend $250 on and have it run all games for it perfectly for 7+ years, be comfortable playing it in a nice living room chair of bed, and have a half assed $300 Computer for 5 years that I can surf the web with (maybe not play new games on, but the discount ones play fine) and use as a multimedia hub.
Home PC's are essentially inefficient to run games on, they have to run an OS, Virus scan, other assorted background tasks, and on top of that a game on a processor not optimized for gameplay.
