Chuff me, when they run out of new ideas they'll try and sell you a "retro" telly like this, black and white and you can hardly see the picture. Then the process will start over again.
All these "advances" in tv technology are a load of rubbish designed to part you from your cash. Once you have a flat screen 1080p tv I really don't think it's worth buying anything else. Go for a nice holiday somewhere.
