I don't see what the big deal is. they have them at best buy, so you can go in and see one. The picture is clearer and more real looking, but who cares? I don't think its worth spending 5-10x as much as an HDTV. big screen plasma = $10k, big screen HDTV = $2k, regular big screen = $1k. Maybe in a couple of years it will be worth the extra money.
On another note, 32' tvs are down to about $340 now. Kick ass.
