I've read a lot on this forum about screen burn and how long people watch their plasmas for etc?? Being new to this plasma lark, when my screen arrives, am I wrong to assume that it can be used in exactly the same way as our current tv. This means watching a lot of sky, and dvds and the unit being on for long periods of time... Can't see me having to tell the wife to go and watch Eastenders on the portable, because this new super duper plasma i've bought can only be on for a couple of hours a day!!!! How do you use yours???
