Does anyone own/use a projector with their computer/Max? I searched the forum, but only very old posts came up, and I have NO idea what the current situation is in this market. I'm interested in buying one (

1) Wifi projectors? Good or bad?

2) I have a 2011 27 inch iMac...is it possible to extend your desktop to a projector? Show jitter windows JUST on the projector? I want to still be able to use my computer for normal tasks while this is running.

3) It would probably be on/active for most of the day...possible? Will the bulbs just fry with this much use?
