1. When it comes to USB drives, I can just plug it into my Mac, put the file on it, and be on my way, right? But what happens when I go to a school computer, that runs Windows, how do I use the file? Is there some alternative? 2. For projectors, how do I hook my MBA up to one? Our school has a projector that any student is free to use, but I'm not sure how to hook my MBA up to it. It's one of those ones that shoots light onto a white sheet to display the thing. Is it VGA? 3. In regards to Keynote, if I have a screen with say, "What do you expect the average growth in one year for this company to be?" and I want it to display the answer within the same slide by say, using an effect to make it appear, do I need to create a new slide and copy the previous into it, or can I make the transition part of that actual slide. And I can use an Apple Remote to advance to the next slide/transition, right?
