It's been pretty good in Dallas. Most athletic events are in 1080i HD and look pretty sharp, plus they are widescreen

The big 4 stations also have a lot of TV shows in HD, like Boston Legal, Lost, Grey's Anatomy, etc.. It's nice to have a crystal clear 50" display that I can view from across my living room without using my glasses.
Oh yeah and I watched Fashion House last night and there is nothing like scantily clad gorgeous women in high def!
Satellite TV in comparison looked like shat on my big screen. Satellite only looked decent on 32" and lower TVs. It's compressed so any size over that looks like they ran the signal through a screen door.
