I see. I guess I was just thinking about it from my perspective. I have a desktop with dual monitors for "regular" computer stuff. Then I have a spare low profile desktop in my entertainment center that is hooked up to my TV. I have a wireless keyboard with an integrated mouse. I use the computer hooked to the TV to spin MP3s through my stereo system, surf the net from the couch, watch videos on the big screen and play old school games.
It sounds like your main computer and your TV computer are one in the same.
