Right now I have the HP wireless elite desktop k & m. The mouse gets interference even 4-5 feet away at times and will lag or skip around, and my pc has wired Internet. I also have it plugged into the front of my pc.
I want a relatively small / normal sized keyboard and mouse that is wireless (I play from my couch). It should get no interference up to 15 feet. I want to be able to plug it into the back of my pc, and it should be sufficient for playing diablo 3.... Does this exist?
