If I gave these requirements to my parents they'd go to a random computer shop and come back with probably a random 13 or 15 inch DELL. And that's what millions of people get at work as a standard supplied computer.

I am not saying the mac isn't good at filling that niche, just that people who really don't care about computers also don't care if it's a mac, and will probably be fine with any recent default configuration machine from a major maker.

PS: > bring your Mac to the next Apple Store

You need an Apple Store. In my experience people have come to terms with shipping devices and waiting for repairs. Cloud sync helps a lot in that respect, as keeping another computer around has become decently manageable.
