Post Production Engineer/Technical Director here, built several million dollar facilities in NYC, worked lots of commercials and a few docs here and there (latest one airing on ESPN 30for30).

Very few high end pros use Adobe Premiere Pro as it's all the worst parts of Avid and FCP without the good sh!t, although the tiny one man shops seem to love it.

Any shop that is busy uses tons of firewire drives and big ass SANs, internal drives are mostly for the OS and occasionally often used assets.

Apple isn't perfect, their QC has definitely faltered as they've grown, but in Post it's a shit ton better than Windows, even facilities that aren't using FCP prefer Avid and After Effects/Photoshop for Mac. Windows is bigger in the 3D world, Linux is popular for color grading and compositing software.

Hell is a Post Facility relying on Windows. I used to know a few, never liked working for them, always seemed to cut corners if it saved a few bucks. That's fine if you're cutting web videos or local spots, but not when you're cutting Fortune 500 national brand campaigns.

As far as looking at these problems pragmatically, you can't rely on an OS that's going to crap the bed because the editors spent their down time trolling shady websites.
