My PC is my TV.
LG L226WT LCD (high def? No idea), with a Hauppauge WinTV-PVR 150 tuner (standard def).
My parents have a 32" Sony Trinitron-tube TV. They'll probably get HD when the cable or TV companies show up at the door and threaten to kill them unless they move to HD. The way my family's eyes are, HD vs standard def wouldn't make much difference anyway. I'm nearsighted, but it's so near that once anything gets beyond 10" from my face, I can no longer focus on it clearly. 25yrs old, and probably looking at bifocals soon.
