whill it's just two less cords to worry about when you are moving stuff aroun. also, don't get one if you are going to game, there is a slight delay that IS noticeable.
well, don't get a crappy mouse and keyboard . . .
if you get something like the logitech mx duo or good microsoft one, they there won't be a lag or anything . . .
I have a Logitech MX Duo and I love it to death!! I have yet to have any problems with mouse or keyboard. I am also pretty heavy into the gaming and have never had a problem. I highly recommend it
