My only real thought on this is that, from a purely PC-gamer perspective, you have a lot less options for consoles, control-wise.
One of the worst games I ever played was a direct port of some fantasy RPG type thing (I forget the name of the game) which was obviously a direct port from the console. To me, having a keyboard with, what, 50 buttons, means I have a pretty large array of commands I can easily access. When I found out I could (or rather, had to) limit myself to the E button being "case sensitive" and "detecting" what I wanted to do with a certain object, I thought: "But why? When I have an entire keyboard, four mouse buttons and the entire alphabet at my command, why can't I choose my own layout?
To me, console games always seem dumbed down, and I dislike that feeling, because it feels like these games have been stripped of anything unnecessary to make sure it would control just somewhat properly. It's sad, because I don't think console gamers are necessarily any stupider than other gamers, they are simply portrayed that way because of their limited control scheme and general clunky UI in-game.
Some games are best played on a console. Fighting games like Tekken, most sports games (except racing), and generic hack'n'slash like Devil May Cry (I paid $10 for a port for the PC to try it, and it was $10 too much). But for RPGs like Oblivion or Morrowind, the control scheme simply isn't big enough on a controler to do the game justice. I don't think it's got anything to do with a learning curve (except that console gamers may be slightly more casual gamers, but that's not the same as saying they can't or won't pay attention to text or tutorials) or lacking patience at all, simply the inherent limitations of the console controlers.
Suffice to say, gaming is, for me, a PC thing.
