they spend extra because its trendy.
It's this assumption that irks me, I think.
I won't deny that that's part of the charm - it clearly is for a large proportion of Apple's market. To deny it would be daft.
But really, what makes up the price of Apple kit is the quality, the design, the style, the aftercare, the completeness, the reliability, the OS, a million things.
The print and design industry runs on these things. To dismiss them as trendy computers for people who live in studio flats in Islington is naive. Macs do serious business!
That the hardware itself encourages you to lick it is neither here nor there, but it certainly forms part of the appeal.
For people like you lot, i.e serious computer users, the proof is in using it to do something useful. When I was in newspapers and print, I abused my Macs terribly, and in some cases it was relatively ancient kit - but it did what it was told, faultlessly, despite putting up with hamfisted operators (me!) asking way too much of it, by yesterday.
