Over at engadget you can find this excellent article that easily explains why DLP, one of the many new HDTV formats competing for your wallet, should be on your list of things to drool over:

Q: Why DLP over other technologies?

A: There are two main reasons why people buy DLPs over other technologies such as plasma or LCD. First, they don’t wear out. DLP projectors can’t suffer from burn-in and there is nothing to fade or wear out. The picture from a two year old DLP Television (with a new bulb) will look exactly like the day you brought it home. Second, there is no screen-door effect*. The mirrors on the DMD are very close together. This means that more of the screen is used to display content.
