I agree with Shifty in that PC gaming can be pretty awesome if you are a bit tech savvy (or alot) and you have some money for building a nice rig.
I subscribe to both PC and Console gaming though.... I have my Xbox 360 setup in my theater room with a big screen and surround sound.... then I have my gaming rig setup at my desk with my nice chair.... I guess I have always used them for different types of games and different atmospheres....
I think you could make the argument a PC can play virtually any game easily since it has the power and you can hookup console controllers to a PC, but I would never want to try to play an RTS on a Console....
I like both for different stuff.... Mass Effect on my Xbox in my theater room.... Total War on my PC in my command chair...
