Ill go right out and spend 40 - 70 dollars on a 360 controller/ wireless adapter when I have a perfectly good mouse and keyboard. </sarcasm>
And how does that make sense?
Like... if you have a fork, does that mean that you'll never buy a spoon?
If you're an avid gamer and use your PC for gaming, a controller can be a really cool thing. And in todays world, if you have one of the consoles, you can reuse your controller without a problem on your PC anyway.
@Sponge: See? The dongle is fucking awesome and the 360 controller is really worth it.
