I think that those who are PC exclusive, and gamers (as opposed to casual gamers), are PC exclusive for many more reasons than just the controls.
PC Platform pros:
More powerful hardware / better graphics.
better controls (for many game types).
more games.
a better quality of game (more depth).
steam.
better internet based gaming including MMOs.
better internet gaming community.
indie game developers.
advanced configuration (e.g. config file settings, dev console, drivers and wrappers, overclocking etc.).
patching and DLC.
modding.
community run dedicated game servers.
fun of custom building your gaming rig.
cheap games, especially via steam and other digital download
Console platform Pros:
easy and fun to multiplay with mates round the tv.
more comfortable to game on sofa.
games tend to be less buggy out of the box / no compatibility issues.
some big titles that aren't available on the PC.
better at games that play best with a controller e.g. racing games, beat e'm ups - I think that's down to standard hardware/controller.
not crippled with DRM (to my knowledge).
The lists aren't exhaustive, but my point is just that the PC offers more benefits than just the keyboard and mouse controls. The console platform does offer some convincing benefits over the PC platform, as I've outlined above but for those PC gamers who haven't been tempted thus far a keyboard and mouse isn't likely to swing it.
