I stopped by the Circuit City in Glendale and noticed that they advertise the HDTV’s in two fashions (720p & 1080p). Every model I cross referenced online that were labeled 720p were also capable of 1080i. I think it’s fairly obvious that this is a marketing scheme to make the 1080p screens look 360p better in peoples minds. Forget the fact that there are no native 1080p broadcasts. . .
Word to the wise, do your own research before spending a ton of money on an HDTV. Do not rely on commission based sales people.
