An Audi SUV's price isn't justifiable given almost every use case for a consumer automobile, but a lot of people enjoy the experience and find it worth paying tens of thousands dollars more than a Camry. By comparison, if you work on a computer for several hours every day and prefer the ergonomics of a Mac, spending an extra $1,000 is a pretty minuscule premium.

And I say that as someone that happily switched from a Mac to a PC I built a few years ago - I like getting the maximum grunt for my money.
