FCPX may not be right for everyone and I might not even be classed as a 'professional' any more for using it. But it worked great for me. And where appropriate I'll be using it as much as possible.
1) The whole 'pro' thing seems to be a bit of a misnomer:
en.wikipedia.org/wiki/Professional
2) Very happy to see that you're getting good results with FCP-X in the 'fast turnaround' corner of our market. I've been cutting an Event Summary on FCP7 last week, and was missing skimming and easy media management (when you're getting AVCHD and SxS cards thrown at you, plus DSLR timelapse and H.264, all just raw stuff and no shot logging).
3) I hope Apple work with camera manufacturers and we get support for things like Shot and Essence marks - i.e. the metadata we can record TODAY that marks whole clips as 'good' or 'use' and also mark points WITHIN clips where something good happens (these are the 'Essence' marks - separate from the Shot marks). Of course Vegas recognises these with Sony camera footage, but if FCP-X is all about Metadata, this is data we can USE!
