Now this was a surprise submission considering Acer has never sent us a projector for testing. We always had the understanding that BenQ was looking after this area and Acer would stay out of projectors. In any case, we are now aware they know how to make an ultra-portable projector.
The PD321 was the second smallest projector coming in at 1kg. It features standard connectors on the back an easy-to-use menu system and is capable of doing Picture in Picture (PiP).
The PD321 is rated at 1100 lumens same as the Infocus but it happened to be a lot brighter and sharper. The only real issue we had with it was that it was noticeably brighter on one side of the screen.

Interesting and helpful article. I am interested in finding more information on the wireless projectors that use the 802.11b or g. What are folks saying about them. Are they cost effective?
