First of all, I'd like to thank everyone for their responses to my question about using Final Cut Express on my iBook. I thought I'd post the conclusion to this thread... I spoke to Apple Customer Support and they assured me that even though the "Before you install" document reads that the software requires a dual USB iBook, it will still work on my clamshell iBook. I installed the software last night and it seems to work fine. I haven't had a chance to play with it too much to say anthing about performance, but it looks like a great program. I watched the DVD tutorial that comes with it and it makes iMovie look like a toy. I'm excited to start using it. Thanks again for the responses. Dave.
