Yes, I had a look at the forum....great stuff!
I have seen some 7" XGA screens (for DVD players in cars). These might be the basis for a compact projector. I noticed one called a "Liliput" but the forum for this is locked:(
I also noticed the Liliput screen for sale on Aust ebay for $299...its got me thinking...
I haven't found anything about how they perform in normal lighting situations yet.
Cheers
