This is too bad. I travel and give presentations, always with Keynote, and I always tell them where Im presenting that I can use their Mac for my presentation, just so they have the trial version of Keynote on it, which doesnt let you save or create presentations, but does let you show them. Getting rid of the trial version thus reduces some of the usability of the paid version. Its a great program and people inevitably ask me what software I use after my presentations. Apple should let as many people get their hands on it as they can.
