I've never owned a Samsung TV, so when we moved to the UK about a year ago I bought one. It was cheaper than the comparable Panasonic PDP, and the apps platform was light years ahead. Unfortunately it broke (line of random pixels along the left) last night (or more specifically I noticed that it was broken last night), and even more unfortunate Samsung won't do anything about it. On the plus side, it wasn't that expensive and Samsung's HDMI CEC implementation baffles the mind so I won't mind replacing it that much. Even more important, I learned something about Samsung TVs - they're only good for a year :).
After complaining about this on Twitter, Samsung agreed to replace the panel. So kudos to them.
