It's on the more technical side. Like doing custom settings etc. can be really hard if you don't sometimes pay for some specialized software. Not the OS itself.as someone somewhat "deep" into the Apple ecosystem (depends what you think it means), I still think the iPhone 7's removal of the headphone jack was a bit silly. can't be that obsolete when tons and tons of devices still rely on it.
I do hope it pushes the development of bluetooth headphones more however, to make them better. until then, /shrug
mind if I ask what you mean? because macOS has been free of charge for a while now. Apple's been making some of their consumer applications completely free too, like the iWork set.
