Yes, this is part of the genius strategy that most people don't see. There is an entire generation of people growing up where iPhones and iPads are the computer. Many of them also don't even know that there is a difference between a mobile device and an iPhone. Android is this weird sort of alternative that nobody uses, and Windows is this "PC" thing which they've never used but they hear that some people use for gaming. To these people, the Apple way is the way, and converting them to anything else will be nigh impossible. The current professionals that find iPads insufficient will age out, and the next generation will consider them the standard workstation.
