Why bother buying a big screen that takes up part of your wall, when you can buy a cheap projector and take up the entire wall?

Many people fantasise about owning a plasma screen because of the massive image sizes and are getting excited because the prices are rapidly dropping, but in the projector world the prices have already dropped so far that for under a few grand you can now buy something that projects an image larger than four plasma screens. Compare that to the price of a plasma screen and see which way the scales tip.
