Beam me up, Scotty

And now you just wonder what the hell should this title mean... Well first thing's first: we need to do a presentation for psychology after half term and I am preparing it at the moment. But the problem is that I am so used to work with Apple's Keynote that I don't really like powerpoint that much and I don't want to convert my beloved presentation into a .ptt file :P
That's why I bought an adapter for 3£ on eBay to connect my computer to the beamer.. BEAM ME UP!
