Last month I was able to convince my college's TV studio director to consider FCP X. He held off when it was initially announced, due to people claiming it was "dumbed down" and such. I showed him the current version on my MacBook, and explained how they added back a lot of professional features, including some new ones. He was quite impressed with it, ESPECIALLY the background rendering and 64-bit support. (It somewhat reminded him of the old Pinnacle Liquid Edition software the college used to use back when the college's Fine Arts building primarily used Dell PCs; now it has two Mac labs, and the theater department uses a couple of iMacs as well.)
They plan to replace the early 2009 24" iMacs in the video editing lab at my college's Fine Arts building with new 27" Retina Display iMacs (they're leaning towards the 1 TB Fusion drive model; I heard it's a great Mac for professional video production!) If they do, they are planning to have Final Cut Pro X and Compressor on them, along with the Adobe creative suite (not sure whether they'll still use their copies of CS5.5, or upgrade to the new version.)
Final Cut Pro X is my main video editor for anything elaborate I do on the Mac, especially "YouTube Poops." (I hear many Windows "YouTube Poop" makers prefer Sony Vegas, but being a Mac person, I find FCP X to do the trick nicely.) For most elaborate photo work, I prefer Adobe Photoshop CC. Sometimes I use Adobe Premiere Pro CC for certain video projects. Anything basic I do (like simple vlogs and whatnot), I typically use the current version of iMovie.
