I bought a nice 720p Professional Panasonic plasma back around May, it has never really been used though apart from when I lived in a flat for a few weeks and played Street Fighter 4 a lot.
Since then I moved into a student house and didnt want to put it in living room and I felt that old gaming emulators didnt feel right on a Plasma and even though its thin and flat it takes up a lot of space in my bedroom.
So I got a cheap old fashioned(but model only a few years old) CRT Sony widescreen tv.
Picture is amazing even for avi's, only problem is no component or vga connection so have to use a convertor box which isnt perfect as has juddering and of course the tv takes up massive amounts of space in living room and has its own special glass stand.
I have used my plasma three times since moving here, once watched a movie, once had a movie in background but wasnt paying attention as was on internet in bed, and once when I was testing out my old desktop in living room.
The only things keeping me from selling is price as I am bound to be offered pennies and also transporting if I sold it and that it has good connections to use i.e HDMI and VGA so could just attach laptop if bored.
