I just bought a new 47" Samsung rear projection HDTV. Good beginnner set I think. And since it has a built-in HDTV tuner I hooked up the rabbit ears I had laying around in addition to the cable.
The HD picture is fantastic. I never want to watch cable again. :) Except that there are more channels, but the HD picture over the rabbit ears beats anything on the cable. Including the digital channels.
But to me there's just something wrong about HDTV and rabbit ears. :)
