They didn't do that because it is not what most people want. Apple has to make changes that will sell more laptops to the masses to maximize shareholder value. The niche developer/macrumors posters will never be happy regardless of what Apple does. Better to focus on the 90% of customers who buy products and make up 10% of the complaints then to focus on the 10% of customers who make up 90% of the complaints.
I don’t necessarily agree that it’s what most people want. I think the reason that most people keep buying macs is because of MacOS. It is so nice to have a UNIX-based OS with great UI, so we keep buying the overpriced, out-of-date, defective laptops because we have no other choice. I’m convinced that a solid, secure, reliable and polished Unix-based OS for developers would quickly wipe out a large segment of Apple’s…
We all want a solid and reliable UNIX-based OS, but we also want an OS that won't be treated as a bastard child by hardware and software vendors. As much as we all love the world of free software, sometimes we actually do want/need to use commercial software as well.
Apple has given us what we fundamentally want, so we just put up with all the baggage that comes along with it. After all, what else are we going to do? Use Windows?
