wireless Keyboards are good for quake (unless they run out of batteries in the middle of a match... its kind of weird and confusing, not sure what happened hehe - btw 5month batteries in there, so its not like its every month or anything).
Wireless mice.... most reviews and all wireless mice i've tried suck for gaming. They're low refresh rate or what not, and not very accurate IMO, and slightly laggy maybe. But I'm open to other opinions, problem is I haven't heard many good things :/
So wireless keyboard, tailed mouse, maybe look at a remote for controlling things for away
