Bear in mind that the cheaper end (although one could hardly call data 
projectors 'cheap') of
the projector marlet delivers a screen res of 800 x 600 as well as your

I'm sure you are; however more space is a luxury. It is a discipline to 
confine oneself to
a smaller screen size. However, if one remembers what wonders were done 
with sub 640 x 480
screens, one will realise that a lot can be done in 800 x 600; just 
don't display the end result
on some whopping-great screen as the pixelation will make your eyes go 
very funny indeed.
