I was in the market for a new TV to replace my 32" widescreen CRT by Goodmans before Christmas. Before I saw this product, I would definitely not buy a plasma and wanted an LCD, believing that they were superior.
I had looked at LCDs on the Internet and then went to my local shop, Stuart Westmoreland. The LCDs looked brighter and, at first, more impressive. The BBC HD preview was on, which was good because it showed a mixture of programming, e.g. nature and tennis.
It was clear that the plasma gave more natural colours and, on the tennis, the motion was much more fluid compared to the LCDs.
The new generation of plasma screen is not plagued by the problems of the days of old. I've had images on my for long periods of time and no hint of screen burn. I always make sure I turn off the TV just to be safe if an image has remained for longer than 10 minutes.
I think plasma is better than LCD (whereas the HD performance is of similar quality, the standard-definition performance is much better) and will maybe only be threatened by LCDs with improved contrast ratios and the new LED TVs.
