Plasma still has the edge on LCD for picture quality at present, The pansasonic LX series LCD or sony bravia D series LCD does have a reasonable picture quality on standard definition material though.
To be honest though, considering most stuff is still standard def, you cant beat a decent CRT. Just a shame no one bloody makes them any more.
I also Like CRT, second to that LCD.
I work for an equipment Rental Company.
Apart form doing big rock and Roll shows, we do a lot of corproate work, so we have about 60 odd plasmas and Lcd's in stock.
Investment in displays are moving more to LCD than Plasma.
Plasma's number is definately up. LCD has improved soo much, many buyers will no longer know the difference.
LCD's dont seem to suffer as much latency as Plasmas, although both improved much over the years. Colour and COntrast on LCD's are just getting soo good, they have to be an honest option.
As for the small = LCD, Big = Plasma, its all total horse tonsil. I think manufacturing costs have dictated that rather than public opinion or need.
Over time LCD's will get bigger.
As for Plasma's running out of gas, most brands quote 8000 hours plus, so at 6 hours a day of TV, thats 1333 days or about 3 and a half years. (This is from very old info, I am sure it has improved)
Most Plasmas and LCD's,run at a native resolution of 1024*768 even though the aspect ratio is either 4:3 or 16:9, irresepective of size. So the bigger it is the further away you need to be from it for you not to see the pixelation. Stand Close to a 65" or 105" and you'll see what I mean.
If you are looking at any display, look at it at the distance it will be in your lounge. Watch both DVD ,as well as broadcast signal, hey bring your favourite Barney DVD. Have the same content running on 1 or two options. Its easy enough for them to do, they usually have matrix switchers at the back.
Sony and Panasonic seem to be on the top of the hill at the moment, with Samsung and LG scrubbing dishes at the bottom.
DONT RELY ON THE MADE TO SELL SLOOOOOOOOOOOOOOOOOOOOW PANNING BIKIN CLAD SALES PITCH DVD's THEY SHOW.
Most are made to bring out the best of a display. If the display is HD compatible/Ready, its probably playing it at that reolution too, so it wont look like that when showing Barney to the kids.
