what an age old debate this is :-D
here are some of my thoughts.
i'm going to be buying a big screen soon, not quite sure which one or which type.
it is between LCD and Plasma.
Originally I wanted a DLP tv, but their viewing angles aren't good enough for me. Not to mention their color isn't as good as a LCD or Magma. Don't try to tell me different. Well you can try, I just won't listen
plasma burn-in, that is mainly a thing of the past. It can still happen, but the duration required to burn an image in, is about 13x as long. But you know if the plasma owner has a xbox 360, that halo 3 radar will be burnt in
one thing I haven't seen is the mention of Direct view lcd vs projection.
direct view looks better than. But a 50 inch direct view LCD is in the 5-8k range. Where a 50 inch lcd projection is in the 1800-2500 range.
a 32 inch LCD is a direct view, which is why it looks so crisp. Where a 50 incher from the same company, won't look as nice and won't really be that much more expensive.
someone mentioned the 50 inch toshiba for 1700 they had on black friday, they sold out of them and I couldn't get one

that is a KILLER tv.
as for getting a tv with 1080p or sticking with 720p
my friend bought a big screen last year when 1080p was going to come out, his TV doesn't have a digital reciever in it. Know why?
because they change the formats so much that it is more economically viable(for him) to just get an external convertor for 400, then when the new res becomes a standard, he just buys another and sells the old one.
shit 480p looks better than anything I have right now, much less 720 and 1080.
