I just recently retired from over three decades of video production. Funny, my home FCPX setup is actually better than the one I had at work. They were all switching to Premiere, which I just don't enjoy working in as much as Final Cut Pro.
Interestingly enough, I've never really cut with FCP....I went from AVID Newscutter > Media 100 > AVID Media Composer > Premiere Pro > Media Composer.
For my music video stuff, I like cutting in Premiere Pro. Syncing music is such a breeze with it. That and AVID doesn't really like AVC files from my webcam.
Anyway, I'm always open to constructive criticism if I'm missing anything glaring. ps - congrats on retirement!
