I've just produced the COW's first tutorial in-application for FCPX. I encourage everyone who has a question about something, send me an e-mail, and I'll either respond directly here, or do a tutorial to show you something you want to see. Let the fun begin.
I would appreciate it if someone created a keyboard shortcut translation. For example, FCPX's "T" key is (trim) is now what we used to call "slip". Experienced FC editors are going to need some help wrapping our brains around the new paradigm.
