Hi! I don't have a mac but being an Apple product I'm sure it isn't subject to Microsoft's mercurial updates. My Chromebook certainly isn't and is quite useful when my Windows laptop acts up.
I do find my Windows laptop to be useful for a number of other things, such as downloading and using a program called Libre Office, which is both free and can do pretty much everything that MS Office can. Also, I can store documents and photos locally as a local backup with plenty of room to spare, as well as using other programs that don't have a Chrome OS equivalent yet. And I can still browse the web when I need to.
Oddly enough, though both my Windows machine and printer are both HP products, I actually had a much easier time setting up my Chromebook to print wirelessly through said printer, as well as a more sure response when printing than I do setting up and printing with my HP Windows laptop! In fact, I still cannot print wirelessly with the Windows laptop because the printer just won't recognize the Windows computer, no matter what I've tried! And yes, the document or site that I'm trying to print does show up in the queue, but the printer claims to be "Offline". So I use a cable to print from my Windows computer! But printing from my Chromebook? Responds and prints right away, no hassles! Very strange.
