Re: That's because
Macs are nice enough kit (I have one at work) - but - the games I like to play are never available on Mac, the electronics design software and CAD in general (Altium Designer, Solidworks e.t.c.) we use does not exist on Mac. So we have complementary windows boxes too.
I also think that Mac feels a lot like Linux - everything works with everything Mac'ish - but with slight inconsistencies that are OK to have for free software, not in a product priced at 4 digits. I think people love the design.
