Mack, I've never been a PC gamer (unless you count the Sinclair Spectrum I had during the 80's!). I like the ease of use of consoles, plus the key word in your post is 'most' games.
With the 360 and consoles in general I can get a slice of PC games (granted, a bit downgraded graphically) and also games which will never appear on PC and wouldn't be suited to it. Also I don't have to worry about upgrading graphics cards, compatibility issues etc which is never a problem with consoles.
I know the PC excels in FPS games and will always be one step ahead of consoles so it may be something to think about for the future, but for now I'm a console gamer ;o)
