Hi Am I barking up the wrong tree thinking that for full classroom sizes, we could invest in a 1024x768 or higher res projector and I could display whatever is going on on my desktop clearly on a humungous screen or at a push, on any well painted white wall? I use my PB a lot for teaching English as a foreign language. I have an extensive selection of material and the kids love doing exercises based on photos, video clips and music (as do I). With a wireless gyroscopic mouse, I dont have to get in the way of the screen to stop and start clips, and I am also free to flick around iLife without having to prepare minutely judged "presentations". With this set up, the PB is an ideal tool for groups of up to 6, but thereafter the screen is struggling for size. I am out in the sticks and am researching all this without ever having even seen an lcd projector! I understand from just reading reviews that DVDs are pretty spectacular as in a home theatre setup, but apart from marketing bumf like "it works great with Powerpoint demonstrations", I cant seem to find any meaningful 3rd party info about the sort of use I am thinking of putting the projector to. Thanks for any pointers.
