I get cable through my school, who I assume gets it from Charter (I think that's the local cable provider here). About 60ish channels, with a few inserted by the school to broadcast events and such.
The school seems to be on a plasma-screen buying frenzy lately, though: they're popping up all over the place (even just to display our digital signage: sounds like a good way to get a plasma TV to die within two years to me).
Plasma-screens don't provide the best bang-per-buck. Most of the schools in the UK have gone with projector systems. For that you get a 100"+ display with pretty decent resolution, and since they use standard ceiling mounts you can easily replace them in a
matter of minutes.
As for myself... We've got 3 "real" TVs (1 in the kitchen, 1 in the spare bedroom, 1 in the living room), and two TV-enabled 'puters. Good thing TV License fees are per-household, not per-TV.
