Hello. I've heard from one person that the days that wireless keyboards and mice were bad for gaming are over, and another that we, in fact, still live in these dark times. I must know the truth! Am I going to have a lag problem, or be changing batteries every other day, while playing games on the PC with any decently priced wireless KB/M? Or should I stick with wired? I have a Logitech MX518 that I like to use, so if wireless mice are still bad but wireless keyboards are cool, I'd be interested in suggestions. Or if both wireless KB & M are bad, good suggestions for wired ones? Gaming isn't my primary concern with the keyboard (I type lots of long papers for school) but minus whale be for mouse.
