Donny: your big screen needs is EXACTLY my point in promoting the much MORE powerful laptop software approach ! In regards to Dave's concerns about the laptop being to easily knocked over - there could be a way to insure a solid & secure placement right on top of the keyboard controller (clamping fashion or other). This clamping feature might even be included as part of the keyboard controller itself. This way the laptop would kind of be integrated with the KB. As far as people looking over your shoulder to see what's on the screen - I make it a rule that everyone in the audience is ALWAYS kept situated in FRONT of me, and never allowed behind me . . . PERIOD. This way I can always STAY focused on the audience and NOT on the screen. If 'you' DON'T focus on the screen, the audience won't either.
