I currently have my PC hooked up to my TV to use as a media station of sorts. However, I usually have problems when I sit on the couch about 6 feet from the receiver. I've used Microsoft- and Logitech-branded keyboard/mouse combos in the past, and most have done the job to an extent, but I'd really like to find a wireless keyboard/mouse combo that will reach 10 feet easily. Any suggestions? Does Bluetooth offer a longer range than RF?
