I'm mostly an Apple user, but that doesn't mean I'm happy.
- My desktop is a 2011 Mac Mini running Windows 7. I find Windows 7 less frustrating to use than Mac OS, and because Windows wasn't pre-installed it didn't come with a bunch of crapware. The problem is that Apple has neglected the Mac Mini line for a long time, and their latest update didn't actually constitute an upgrade. Too bad, it's a nice design but I'm moving on (just bought a PC replacement).
- my laptop is also a Mac, mostly because MacOS is/was much more secure against viruses. Here Apple frustrated their user by not adding a retina display to their MacBook Air line, instead coming up with the new MacBook, which looks great and thin, but sacrifices processor power, the number of ports and the quality of the keyboard. And it costs a bundle.
- as for MacOS itself, it reached a sweet spot circa 10.3/10.4 Panther and Tiger, was good all the way to Snow Leopard, but it's been downhill ever since. For example, their Mail.app program used to be great and now it's really frustrating to use. A lot of UI choices have been a departure from the way it used to be, meaning with each new purchase I have to fiddle with the settings to get things right. And that was usually my problem with Windows.
- I have an iPad Air, and that's a great gadget for playing games and reading the occasional big digital document. Only frustration with iOS is that you can't turn off the OS update notifications. And it pesters you on a daily basis.
- iTunes is a piece of crap. It's bloated with stuff I don't care about, while doing basic things is complicated. It's so bad I don't bother listening to my own music now and I just go to YouTube instead.
- AppleTV was ok until their latest edition which simply refuses to work properly, even after we replaced it with another one. So we went back to using the old one we had.
- iCloud stuff is fine, but their web interface is slow and clunky.
