When I purchased my iBook, I also purchased Keynote. I was excited to use as I use PowerPoint frequently. However, I find that it totaly, well to put it bluntly, sucks. I thought at first it was because I was too used to PowerPoint, but I cannot get it to do what I can get PowerPoint to do. It just does not seem as professional as powerpoint, and I need my slides to look scientific professional. The things I like about Keynote are the transitions and image shadowing. Yet, the transitions only show up on my projector if they are set at 800X600 resolution....and that does not let me use all of the space provided---chemical structures take up a lot of room and I need ALL my space. Am I missing something? Everyone raves about Keynote, but I feel like I just am not getting that same feeling. I can see that if I knew nothing about PowerPoint, that my Keynote presentations would be scores better...but I do know PowerPoint fantastically, so either I am missing something or Keynote is just not up to par. Help! I really want to keep it as I love Apple software, but I cannot keep somethign I cannot use.
