Everybody wants to talk about it, stores want to sell it and vendors want to build it, but the truth is, the whole HD market is still extremely immature, so much that I can't recommend anybody to make the jump... yet.

#1 There's still way too little HD content on TV, especially if you're not a sports fan.  Digital cable quality is crap, especially when you talk about Time Warner.  I can see their compression on my old 25" CRT even on the mainstream channels.  Direct TV is rather good, I rarely see any compression on my old 25" CRT, so I know if I made the jump, I would definitely see the compression.

#2 There's still no consumer priced HD video solutions.  BluRay and HD-DVD are just too expensive ($30 a movie, $300 for a player) for the consumer.

#3 The monitors are still too expensive.  A good HD LCD (plasma sucks, but more on that later) will run you $1,200-$1,500.  Considering you can get a nice looking 30" CRT for $299, there's no comparison here.

#4 HD quality DVRs aren't common or price friendly, yet.

It's these 4 basic problems that lead me to believe we're still years away from true HD adoption.  The screens haven't hit the price sweet spot.  When you can get a brand name HD screen for $499 that's widescreen and 32", then people will warm up to the idea, and by then, maybe everybody else will catch up too (cable tv, HD videos, etc).

And as for plasma, even though people like to say it, LCD is a very good technology, the old problems about slow redraw rates are history and the lack of true black is overrated, especially since most people don't watch TV in a pitch black room.  Plasma chew up a huge amount of power, in fact when I walk past those Dell tables in the middle of a mall's hallways, I often feel the heat coming off of them.
