You don't just buy an Apple iProduct - you embrace the Apple lifestyle.
That's why iPads come with adoption certificates, simply handing over money for one would devalue the whole experience of transferring the love from Jobs to you.
I'm on my third mac (I just can't find a comparable product to a MacBook Pro), but the whole apple lifestyle stuff is a big turn off for me.
If I could get a comparable laptop (obviously by my own preferences) then I'd jump ship in a heartbeat, just so I didn't have to feel like I was part of some Apple fanboy club.
I'm pretty sure that the majority of Apple customers feel that way or at least aren't interested in any kind of "Apple lifestyle". The proportion of Apple customers who are true fanboys is probably no higher than the fraction of Dell customers who are gamers with too much money and completely unrealistic opinions about the relative merits of AMD vs Intel and Nvidia vs ATI. The stupid rich Apple fanboys get more disdain than the stupid rich gamers because the Apple fanboys are more ostentatious and the gamers [ab]use technical terminology that makes them sound less subjective.
I gave up on my PowerBook 12" last year. It had pretty good software, but the hardware was really disappointing. I've bought a Lenovo Thinkpad, put Ubuntu on it and I'm very very happy.
