Want to know a big reason people have been getting Macs, that Apple doesn't like to admit? You can run Windows on them now. The Intel switch made it viable to run Windows on them, natively if you wanted, and good virtualization tech means it runs fast in OS-X. That lets people get their shiny status symbol, but still use the programs they need.
We've seen that at work (an Engineering college). Prior to the Intel conversion, there were almost no Mac users. The thing is engineering software just isn't written for the Mac. There is actually some stuff now, but even so the vast majority is Windows or Linux. Back in the PPC days, there was almost nothing. So we had only really two stubborn faculty that used Macs, one because he did no research and just played around, and one because he wrote his own code and was stubborn. However that was it, you just couldn't do your work on them.
Now? All kinds of faculty and students have Macs. PCs are still dominant, but we see a lot more Macs. However every one has Windows on it. Some it is all they have. Seriously, we have two guys who buy Macs, but have us install Windows on it, they don't use MacOS they just want the shiny toy. A number have bootcamp, and many have VMWare. Regardless, I've yet to see one, faculty, staff, or student, that didn't put Windows on it to be able to do the work they need to.
So that is no small part of how Intel helped Apple gain market share.
