The only thing I can say about the new iMovie is that I absolutely hate it. I’m quite glad that the installer saved the older iMovie so that I can quickly revert back to it if I want to. Over time I may start liking it and using it more, but that currently seems quite unlikely. Though it doesn’t hurt me, another thing I hate about the new iMovie is that it can’t run on macs older than the G5 (Intel came after G5). Enjoy, Alex.
