Think the only problem with projectors is brightness - or moreso ambient lighting dulling down the image a bit, so it'd probably be at its best either at night or with subdued lighting (by closing a curtain or two).

They also tend to have fixed native resolutions similar to PCs, so looks like attention would be needed when buying with regards to its intended use (DVDs, computer projection, etc.).

Can be a bit bulky too, and they do have a fan, although many are quoted to be whisper quiet at around 24dBs. The lamp lifes can be quoted from anything like 1000-4000hrs before they need replacing. The last time I looked into it the lamps were around £60 a pop. This was a few years ago, though.

So for a main TV I guess it'd be a less than ideal solution, but for special events and stuff with a bit of ambience it'd be wicked (especially with surround sound).

You can even project them up to stupid sizes, like 15' x 15' (feet) on the wall!

Noticed there was a pretty funky Sony one a few years ago that allowed you to place the projector off axis to the wall, literally anywhere in the room, and it would project the image as a parallelogram which you could then manually alter various settings to distort the parallelogram back into a nice rectangular image on the wall for viewing. Otherwise you'd probably have to nail your projector to your ceiling to keep it central to the screen and out of the way.
