I agree with you. I've always thought actual "PCs" were much more interesting than this consumer stuff that seems to be becoming very mainstream.
What I like about PCs is that they scale up and for a pretty small price (even for high end machines like the Mac Pro) you put the tools into someones hand to produce images, videos, code, and well, whatever at a professional ("Hollywood") level. You have the capability to do whatever you want.
As long as the capability is there, I really don't care what form factor it takes, particularly if it makes my tasks easier. But what makes me nervous is that Apple seems to be stripping capability in order to appeal to a broader audience, at least based on the minimal evidence that the FCPx incident provided.
I don't care about what is good for Apple. I simply want a sophisticated tools that allows me to do what I do (large scale prints derived from numerous large raw files, videos utilizing processor taxing compositing and filters, coding capable of creating tens of thousands of files that will eventually become moving images, Photorealistic 3d generation of photographs and videos...)
What PCs give people that consumer devices have not reached yet is a tool that allows for some amazing, fully realized (at a professional level) creative activity. Ipads and their ilk seem to encourage passive consumption (I am not saying they are only capable of this, but looking at the top selling iPad apps indicates a "Here we are now, entertain us" mentality.
What makes me nervous is Apple shifting their focus completely to those who consume and ignoring those who produce. If I could make a feature length film using the iPad, or even manage and edit photographs capable of being printed large, then I might not care that the shift is starting now...
