Well the BBC and Telepictures dropped FC and went to Adobe and Avid. Telepictures even threw out Apple computers (great sale!) and went to PC. So at some level, there are those who don't agree with Apple's products, at least for this generation.
One must also remember that editors who work for directors/producers etc cannot afford to use a product they can't present on a big screen, or deliver on a LTO. It's totally different to a one person show like an event/wedding shooter or small indie project.
Visionary product designers are paid big bucks to foresee the future beyond the now or the past. Sometimes to leap forward, it takes to run a few steps back. I had a long talk with a post friend way back in june about FCX and while we were messing with it, we noticed the number of keystrokes that required the 2nd hand support had lessened significantly to the point that it was almost one handed operation, like the input of an ipad or iphone. Is FCX the ground work for things like gesture recognition editing (think Minority Report) I studied waaayyy back in the college as a theoretical interface? Is that even a good thing? Time will tell.
Peter, Apple has been successfully sued for selling products then cutting off support for it. The powerbook G3 was suppose to be optimized for MacOSX, it was advertised as so. But when the code writers came out with MacOSX, the G3 ran like PPC601. That's one example of bad advertising and mislaid promises. My previous posts on Xserve, Shake, FCServer all point to the same MO. Just because it hasn't hurt you either financially or otherwise doesn't mean it hasn't affected other people. When you get this sort of reaction to a lousy piece of software, it's not just internet meme or mob mentality. The product doesn't meet the criteria of many people. Editors aren't always on the forefront of technology since it requires learning and memorization of the interface.
Following your logic, Apple released a program assuming all editors would never need to go back to their old projects AND also demand their clients to accept only file based deliveries, forget the server hardware that Apple sold them just 6 mths ago. Ever had to recut an older program for DVD/online? Or how about an extended cut? Use FCP7 again you say? Why bother when there are programs out there which can do things faster, and natively? Only 3 cameras easily available can actually shoot 4k, yet none of them can be edited natively. Yet they made sure Starburst dissolve was kept and improved. It's one of the most bizzarro "innovations" I've seen.
While the promise of innovations is wonderful, projects that need real tools to cut now are required! And that isn't FCX. So yeah, Apple left many people behind.
