To me PC gaming and console gaming are completely different experiences. One has me sitting in a chair looking at my monitor while using a keyboard and mouse while the other I sit on a couch or lay on the carpet and play.
Some people would argue that you can take the PC to the livingroom or have one there instead of a console but I find it's a chore to try to relax on the couch or lay on the floor while trying to use a keyboard and mouse. And for those that argue that you can plug in a Xbox 360 gamepad or a similar one that doesn't work for every game and removes what is supposed to be one of the big advantages of PC gaming.
I really prefer to play strategy games on PC (they can be extremely cumbersome on consoles) but I also prefer to play action games such as the Grand Theft Auto series on console. For FPSs the gamepad doesn't bother me at all and I have no real preference since I don't have the time anymore to get so involved in a FPS that I would download user created maps (there are just too many games I want to play).
Anyways sure there's a lot of overlap between the PC and Xbox 360, most developers are using the exact same development tools for both so it's a no-brainer to bring out versions for both. But what's missing in this discussion is that even though the same game may be available for both systems some people may just prefer to play it on one or the other depending on what their gaming preferences are.
