A friend of mine spent well over $4G's (yes really) for one of the first 42" plasma pannys 4 or 5 years ago when this was the new 'thing'. Cost him a lot but he has enjoyed it for the last 4-5yrs.
Another friend still has his 27'' from c1995 and is still waiting for the price to drop on plasma/lcds to all time lows. Just before he pulls the trigger some new technology comes along that he has gotta have and the clock restarts. He may end up getting a 50" for about a G but has spent the last 5yrs watch a crap box.
True stories, extreme, and to each their own, but both prices and technology are good right now and its not a bad time to buy.
....or you could wait another year and pick it up for a few hundred less - but hang on, by then 2160P will be the new standard, maybe you should wait until the price on this drops....
