"Ditto and then some. Using PP on a home built Gulftown machine with a FX3800 Quadro, I was just editing some EOS7D footage."
That's the problem with this arguments. People who play at being video makers/editors with home video format. I can tell you that Premiere "pro" has not cut even a minor DENT in any of the professional users anywhere in my city. Be it television, film, commercial. everyone still edits their broadcast or HD on their Final cut station with aja card. Nobody cares about using FCP to edit your uncle's photo camera videos. People overestimate the importance of that "market" because these "editors" spend their non productive days haunting the forums, posting about their imaginary careers.
You seem to be taking the threat from other systems personally. I'm impressed by what people put on screen, not what they used to do so. If I see a technical flaw, I might ask what they used and how they used it, but only to compare the limits of that system for my own potential use.
I've had Avid Film Composer, Media100 and currently Premiere, and they all have pros and cons. They all produce nice images on the screen. I'm looking to buy FCS because I want to see what all the options are, and I'm not married to any system. I've been first camera for Hal Needham, directed Jay Leno, edited a feature film and currently I'm creating an HD piece for Dell, using Premiere. Perhaps your career is way more impressive than mine, or maybe it isn't, but one thing is certain... Using FCS doesn't turn water into wine or straw into gold.
