Well, "mobile OS" can be rephrased as OS for mobile devices. Hope it clariifes.
You've replaced a meaningless marketing term with… the same meaningless marketing term.
Is a laptop a mobile device? If not, why not? If so, why doesn't it run "a mobile OS"?
Windows and iPod software do belong to different classes of OS and are aimed at different computing devices.
That line is arbitrary. Windows runs on 7-inch tablets. iOS runs on 13-inch devices.
Background tasks are quite a different story.
It's the very story you were alluding to.
Because the PC is more complex device than iPad
How?
The iPad's processors sure are quote complex. The array of sensors it has easily beats that on a desktop PC.
The only thing that makes the PC "more complex" is that you run an OS on it that lends more flexibility.
Look at a MacBook One's motherboard, then an iPad Pro's, and tell me what makes one more complex than the other. Nothing.
, its OS has to do a lot of things which are not necessary for much tighter hardware structure of iPad. Therefore, iPad is much more energy efficient and doesn't have to perform many background tasks. Thats one of reasons for limited multitasking as well.
That's circular reasoning: it has to do less because it does less; therefore, it can do less.
No, it's purely about expectations. Expect the iPad Pro to do more, and it'll have the same complexity as "a desktop OS", because there is no freaking difference whatsoever.
iOS works for two reasons: because touch is an awesome intuitive input method, and because they started from scratch and left out a lot of complexity. The iPad Pro, however, is on the very trajectory the Mac was on in the late 80s. That's not necessarily bad, but to pretend there's something magical that will keep iOS "simple" sure is.
The last words probably could be interpreted that way. MS's approach to windows everywhere is a catastophe because all devices are different. Its just like having one grade of fuel for all kinds of cars and bikes. But we all know the differences between diesel, jet fuel and premium gasoline.
Apple, on the other way, creates categories of OSes, each very focused on its tasks: iOS, WatchOS, TvOS, CarPlay.
You mean like Windows Mobile, Windows CE for Automotive and Windows Server?
