which is DVD quaility? And the HDTVs have a higher resolution of 720p or 1080i? I don't see how an EDTV can ever look as good with the same HD source as the HD set. They may have a great picture, but that's like saying there's no difference between DVD and HD. What am I missing here?

I don't think they look "just as good" literally but they can be VERY VERY close... (at about 1/2 the price for EDTV). The differences are less noticeable at normal viewing distances than up close. Even HD plasmas don't provide a 1:1 correlation in terms of the number of available pixels required to handle a true High Definition signal. There's some processing magic that goes on within the set to correctly interpolate the signal across the available pixels. Some sets do this better than others so if you take an excellent EDTV vs a less than stellar HD plasma, it is quite possible that the two will look comparable with an HD signal. I know that's over simplified but that's how I understand it.
As for 480p from a DVD player (until the hi-rez players come on strong), I wonder if there's any benefit at all going with a HD plasma vs ED.
In any case, if you go to a store and compare side by side, you will see a difference but I cant' seem to justify a doubling in price to get such an incrementally small gain..... especially while the technology is still maturing and the prices continue to plummet.

  applies to video as well as audio.
  One and a half years ago I went with a bulky CRT based HD-RPTV because it gave the biggest HD picture for the $$$. The only issue I have to worry about is burn-in, so I am limited to the amount of digital 4:3 material I watch over the air. I can stretch whatever non-digital signal that comes out of the cable box, but that's a compromise. I would consider the burn-in issue with my next TV purchase. Even after the so-called “analog shutoff”, most broadcast programming will still be 4:3, with bars added.
  I've read talk of 1080p sets coming available, and there are more upconverting DVD player options. I'm thinking about trying one of those inexpensive NeuNeo DVD players myself. I wouldn't be surprised if HD-DVD players came out within the next year or so. And there is a ton more HD programming now than there was just a year ago.
  One observation about TV shopping. This last Christmas I was shopping for a cheap 27" HDTV set for my son's Xbox setup. I noticed a large difference in picture quality of the same set, at different locations of the same big box store. I've even read of store personal "tweaking" certain sets to push sales toward a different model.
