I doubt this will help resolve anything, but here's my two cents (or 20 cents, because this might end up a longer post than I thought):
Let me preface by saying that I'm not such a fan of Macs, or Apple in general. I gladly use a PC at home because I feel I can get more out of it for less cost than I could ever for a Mac. HOWEVER, I have used Macs and FCP at work for years, and am as comfortable with that as I am with Premiere on PC (haven't learned Avid yet).
That being said, my opinion is this: "A good craftsman never blames his tools." (In this case, "tools" being the software, not specifically the platform)
The differences between FCP and Premiere (or any major Windows-based NLE) are so miniscule, that it really doesn't matter what you use. It's all a matter or preference. If you swear off one platform as being unusable or inadequate, than perhaps the fault doesn't lie with your software.
There are other things to consider as well, aside from cost of the systems. Avid is still (I believe) considered to be the norm for studio films, although FCP is certainly making strides on its own. Then again, Avid can be used on either platform. Personally, I find PCs easier to upgrade (important for video editing) and overall more versatile, although Macs are generally better (in my opinion) for running specific tasks (for example, having a system that was only used for editing).
A small, semi-related pet-peeve though; The Mac commercials are a joke, portraying Macs as some sort of unfreezeable, virus-proof, realm of creativity that PCs cannot compete with. I get it, it's supposed to be clever marketing, but I've used Macs enough to know that they have plenty of problems as well, and I'm not just talking about thir refusal to put a physical "eject" button on the tower. Personally, I'd rather have a PC completely lock up on me (which, by the way, hasn't happened in years), than have to stare at that cursed "pinwheel" for an hour without being able to "force quit," eventually having to power off the computer and lose my recent work. At least with the PC I'll know why there was an error... but I digress... That's more a statement on my feelings for Macs, and unrelated to the FCP software itself, which, as I said before, is prety much the same as anything the PC offers.
Again though, For editing, one platform isn't really faster or better than the other. Use what you want.
Now gaming on the other hand...
