I had sentimental reasons for preferring a plasma TV. I studied engineering where the original tech was developed, and one of my classmates led its commercial R&D and licensing for many years.
But when it came time to get a TV display again (after not personally having one for several years) I went looking in the stores, paying special attention to the plasma displays and comparing them to the LCD/LED models.
Over the period of a year and a half, and observing a dozen plasmas set up in half a dozen stores, I consistenly noticed poor contrast from the plasmas compared to the others. Every single plasma had a greenish tint where the image should be black.
Sabotage? How could it be occurring in every display unit in every store over such a period of observation?
I finally threw in the towel and got a Samsung "LED." (I wonder what the'll call real LED TVs when they arrive.)
A little off topic, but I also got a Samsung receiver that plays movies from the internet. That plus my DVD/Blu-ray collection are all I watch.
I have a Netflix on-line viewing account, but many of the shows are difficult, some impossible, to watch because of hiccups in the transmission. A friend has a Roku box which apparently fetches and stores entire programs/movies ahead of time, so you don't see the transmission hangups.
I had to hardwire my (also) Samsung BR player to my router to stop the hiccups. I tried everything, but using the wireless, Netflix choked from time to time.
