Wireless Keyboards
 

I've been asked to pick out a new wireless keyboard/mouse for the conference room at work, and I'd like some advice. The PC is located behind a wall, and the keyboard will be at the far end of a large conference table, so first and foremost I'm concerned about range. Is bluetooth better than RF? I'm looking at the Logitech MX 5500 as the best bet, but would an RF model have enough range?
