mouse and keyboard?

[wupwup]

i know nothing of them. really. but i will need new ones. how responsive are wireless ones? from what i have seen they are fine but a lot of people say they are bad, esspecicialy for gaming. and this may sound realy strange but i dont have a desk, so i will be using the chair arm as a mouse mat (i realy have no other option). it worked fine for my old mouse but badly for the one before that. how can i tell if it will work? thanks
