It would probably be fairer not to compare Apple's products today with Apple's products from yesterday, but its products today with other companies' products today. As technology and tech culture and users evolve, so too do the interfaces. Now I have not used a Windows computer in a couple of years, but when I made the switch to OSX, I found it much easier and more instinctive to use. I'd probably say the same about a Windows computer from 2 years ago vs. an Apple computer from 15 years ago, which like in this article, is an unfair comparison.
When I switched from Windows to OSX, I was constantly frustrated by the way Apple chose to organize things. I hated having the menu bar be on the top of the screen and not part of the window for example. Trying to take a screen shot was impossible without google. It was just as least as difficult learning to be productive on a mac as it was when I transitioned to Ubuntu.
I've come to believe that there is no such thing as a universally intuitive interface - consistency is achievable, but everyone comes to your interface with a different background and therefore a different sense of what is intuitive.
I find Apple's use of the trackpad for swiping between desktops or between full-screen apps to be much quicker for navigating an environment than the alt-tab or mouse use on Windows. Perhaps Windows has improved to offer similar Apple navigation techniques, but I really like that when I switched to OSX. I also think Time Machine is one of best native OS tools I've ever seen, painless incremental backups with no effort by the user.
I came to like things about OSX also. In particular I liked the Ubuntu-style Spaces. That doesn't mean they were intuitive; it took effort to learn the Mac milieu.
