So what's you're saying is that a Mac makes a shiny Unix terminal, being a commoditised NeXT box. And that you're likely to find them on the laps of attendees at wankfests, but not doing the interesting work.
I agree.
You could credit NeXT for building a userfriendly Unix desktop with a poor man's Smalltalk, and say that this makes for a reasonable workstation.
But Apple isn't producing anything new and interesting for producers, is it? Really, I've tried to take an interest in Grand Central, in OpenCL, but it's just... nothing which hasn't been done better elsewhere. Apple just don't do research and they don't implement for researchers or other producers. Hell, it's a common complaint. When you contrast with MS or IBM's research output, it's fairly easy to see the difference in culture. Apple's had this perpetual thing of wanting to be cool, but it's never matured to saying, "I want to create something substantially new."
Have you ever used Microsoft Bob? The experience just reminds me of an Apple iDevice.
