It all comes down to whether or not the system holds enough value to the user. For some, it's valid, while others will finally get off the Kool Aid, and move on.My personal opinion, is never plan too much for the future, especially so for computer systems, I think I should add, especially true for Apple Systems. What to do? We love the Apple OS and the design that Apple has come up with. To a certain extend, we are happily being "con-ed".
Financial circumstances will be the catalyst for most, but the technical issues are beginning to become rather poignant, as the issues are intentional or just a total lack of interest (i.e support). Combined, a lot may begin to question the value, and re-evaluate their loyalty to Apple.
Keep in mind, their focus has shifted from computers to consumer devices and services (i.e iPods and the iTunes store, and was repeated with the iPhone and apps site). What computers they're giving real attention, are the consumer models. MPs have become more of an after-thought lately.
The high temps with the Quicktime X code with less than 1% usage with the '09's is a good example. It's still not been addressed.
From a simple, technical standpoint, no. But there's other issues involved, and economics is related in some manner
You're talking about software though (i.e. SDK's they make available). For hardware, 3rd party developers are on their own. What few products can actually boot in EFI, were done by the companies that developed the product, not Apple (via a licensing agreement).
