I used one for a couple of years, as shown on this post in one of the "Supurb owl" threads:

The DLP projector developed a large number of missing pixels over time, so I junked it and replaced it with a 24" LCD, which is much brighter and much higher resolution (and cheaper than the projector). I still use a very tiny pico projector in the bedroom (nice, because it is quite dim) but it is also now missing a number of pixels. Bummer! Not recommended!
Edit add: old thread and pix of the Pico:

This is the projector that was used in my "computer room":
