I gotta brag on this for a second. I'm in my Mom's living room which I have setup as a true computer/multimedia crossover heaven. Let's look at this system:
A good CPU (Athlon 2K, 60 GB, 512, dual g4 440s, tv tuner, CDRW, DVD)
Dual 15 inch LCDs
27 inch TV
Logitech z680s

I ran wire under the carpet and everything... well it works the way it should. Computer on the TV, TV on the computer... recording capabilities, playback, good sound, secondary sound, tertiary sound... it's just good stuff.
