Great scam isn't it? Look at our shiny new thin TV's, great picture, a zillion pixels... Oh, the sound is shit because the speakers are on the back and are the size of spam tin lids, so you'll need to spend more money on a sound system.
Christ I sound old. I'm 20!
You can get a reasonable sound bar for about £100 if you know where to look. We have a Philips one in the front room at home and it works pretty well, has a small subwoofer attached. Takes the sound from the TV via an optical cable, but it also accepts Phono (red and white), 3.5mm and coaxial. Much better quality and volume than the TV speakers.
