I understand what you mean, there was certainly a pretty big backlash upon its release but I think a lot of the uproar was justified,
I don't do any video editing but work with a lot of editors and they all seem to tell me the same thing, some great workflow/interface improvements but some massive downsides that make it unusable in its current form.
To some people, this was clearly the case. But their existing FCP licenses still work, so there's no immediate need to upgrade - check out the new version on the side, and over time, when it starts to be able to fullfill your needs, switch. If for whatever reason it is not a viable opion, then people can either stick with FCP for the time being, which is getting increasingly out of date, but eventually sooner or later they'll have to switch - and there's no doubt Premiere and Media Composer have gained users since the FCPX release.
However, Apple have also sold quite a lot of copies of FCPX, too...
Not being able to load old projects was pretty high on the list but my biggest one was no OMF support as this was a feature that is pretty vital in my workflow. I understand there are workarounds but it seems like some of the pro features were sacrificed.
Sure, and we all have different features that are important to us. Remember, this is a ground up, complete rewrite from core architecture up - that's a massive design and development achievement, and resources are finite - even Apple's. It's simply not possible to do everything at once, so you have to prioritise. Sure, to some editors, they would demand that Apple's priorities be different, but it is what it is. And Apple seem to be working quite hard at releasing timely, free updates with major new features (which up to now, they had a policy of not doing - they'd only release bugfix and very minor feature updates, and leave the large new features to major releases - mostly starting with reasons of Sarbanes-Oxley).
Anyway, I don't want to threadjack too much (which I probably already have, but...)
And yes, I would have loved to be able to import FCP projects on release. At least we can now, with an inexpensive app...
