This isn't really news. OS X is a good working unix, it is built and controlled by the same people who build the hardware. It's basically fully integrated into the hardware. It has always had a very clear separation of user and system space and Macs aren't plagued by bloat and shovelware.
You get a mac unpack it, start it and it works. That hasn't changed in decades and holds true to this very day. Not so with a PC. Just watching my colleague hassling with Windows 10 and Office365 at my shop has me stand in amazement over the eternal shittyness of the MS provided solutions that apparently holds to this very day as it did in the Windows ME days. Even today you can't get a basic Groupware from them up and running without a total messy frustration ensuing.
I remember thinking about the brand-new first ever iMac and noticing that you could get one, start it, and didn't even need to adjust the CRT monitor or resolution. A godsend for ordinary users and maintenance personnel. That type of integration and result oriented setup was lightyears ahead of any ugly clunky Windows box. And it still is.
That they are cheaper in maintenance is blatantly obvious IMHO.
A windows PC that doesn't suck is still a rare thing. Probably these surface books from MS themselves are what comes closest to a MacBook.
I've said it in the 90ies and it holds true to this very day: In terms of basic system integrity Windows combines all the disadvantages of Linux with all the disadvantages of a Mac. The only reason ever to get Windows was and still is to run programms on it that wouldn't run anywhere else. And those are pirated software, Games or some obscure CAD program for engineers that don't know anything other than Windows.
That's why Google is moving into their Groupware and productivity space and Chromebooks, as the poor mans mac, are taking over.
Not that I like the prospect of Big Google watching everything, but anything that removes MSes abysmal model from the body public is a good deed. It's not that MS would be any better. Only with Google at least it works and you don't have to pay for it.
My 2 cents.
