It's pretty simple to use, although I did find it quite helpful to watch the how-to videos on the website. I didn't watch the videos with the announcement, so I don't know how those compare. But I've found it to be an extremely useful program. I have the Mac version, and I'm very tempted to put the beta on my PC so that I can go back and forth between computers.
**And having just watched the release video, you could definitely watch the basic Mac tutorial to learn how to do quite a bit of stuff. Plus it's got a few things I've not used yet, because 2.0 for Mac isn't out yet, although it won't have all the same features.
