Not really desktop but kind of appropriate
I bought an projector projector last night for AU$250 (about $200US), pretty happy
It's 1pm here so there's too much ambient light but Mariokart DD was definitely playable. Looks much better in darkness, and for the price I'm not complaining. It has a stupid proprietry VGA connector adapter which is fucked (no red channel) so I'm going to have to fix that.
