I bought a converter and an indoor HDTV antenna to check it out for fun. Granted I live on the first floor and not on a hill, but my conclusion is, you need a real antenna mounted on the roof and pointed the right way. Analog TV gets snow if you don't have a good signal, but broadcast HDTV just doesn't work. Of course most people in the city typical have cable TV to avoid this kind of thing. I'm kind of surprised that comcast and their ilk aren't trying to make more noise to get people to upgrade their service, but I think the majority of their channels will be standard definition for years to come.

Peersonally I think that standard def signals look pretty bad in hi def monitors. 5.1 surround sound is kind of fun though.
