The only annoying thing is that most console to PC ports are terrible (mouse acceleration, low texture resolution, lots of areas where the games look awful because a console can't handle as much as a modern PC but the developers didn't bother improving anything for the PC port, retarded control schemes, bugs, push the start button/insert coin .
Anyway... Be careful with the mouse-for-consoles kind of thing... Console controllers rely on mouse accel (well, controller accel I guess) due to their limitations.
That will drive you absolutely crazy when you're using a mouse, and unless the console game you want to play was developed with a console mouse as a controlling option in mind, I doubt that you can turn it off... Unless maybe you can do so via the console OS?
That being said, I have never tried a console mouse... It's about damn time they come up with mouse and keyboard support for consoles, at the very least for the next generation... There is absolutely zero reason to force people to use the clumsy controllers for shooters, strategy games, FP RPG's etc...
