I'm in the market for a wireless keyboard/mouse combo, and there's Bluetooth and there's RF. Ignoring price, which has better reception/battery life/etc? Thanks in advance.

hmm, BT uses less power, but RF is significantly better with regard to signal and responce speed.
Even the latest Logitech BT keyboard is extremely slow, totally useless for playing games with. No matter how stylish.
I would certainly go for RF when considering a keyboard / mouse. Specially mice. They are waaaaaaaay better in RF than BT.
So i u want games, accuracy (design) or general performance, go RF over BT.
On the other hand, the BT devices (like the Logitech) look exceedingly sexy and more stylish than a very stylish style .. thing.
