I have a friend that uses a wireless keyboard whenever he has his laptop connected to his LCD TV. I have not seen any decrease in performance.
I have no experance with Razor or Orochi brands. If you have the Orochi, use it. Why do you what another one?
I have a laptop, that I play games on, and I want to get a gaming keyboard. Does having a keyboard plugged into your laptop decrease performance? Also, what's a good keyboard for around $100? Is the Razer Lycosa good? I love Razer, i have Orochi, but Lycosa seems to lack features of other, cheaper keyboards...
