I think you misunderstand my question. I am not asking about the 
USB2[S]VGA dongle. It would be nice if cheap adapters were available, 
but the most expensive component is not the dongle but the projector.

My question was about the projector---in particular, how many pixels do 
I need to have a reasonably good approximation of the XO laptop display?
Does 800x600 give poor results? Is 1024x768 enough?
