Is Apple having a laugh? If this was meant to be named "iMovie Pro X" then it's a very good upgrade of iMovie that will excite many - especially newbies to digital video looking to step up a notch. It may also be ideal for some so-called pro-sumers, too. But if this is aimed at professional users - especially editors working in a networked, file-sharing environment where every second counts in post and where content needs to laid back to tape for delivery to the client - then Apple has just given the whole market to Avid and Adobe.
