Um, you're forgetting something. Macs are cool, a PC's have no soul!
But this could be a ford vs. Holden, Nikon vs. Canon, liberal vs. Labor thing, some folks just prefer one over the other
But seriously, macs run "windows" type apps natively, whereas historically, something like 50% of a PC's resources are required to run windows alone, that doesn't leave very much for memory hungry programs like photoshop. Hence the preference of designers, photographers & Musicians for a mac. More bang for your buck, and they look nice too.
Mac even ran a highly successful series of TV ads a while ago about the most efficient computer in the office being the one people most liked using.
As a dedicated mac user for 20 odd years, and recently becoming hooked on astrophotography. It's doing my head in that most of the AP software is written for the PC when 99% of professional photographers (yes I am one of them) use macs.
Arguably, because they're intuitive, easy, and nice to use.
However, ironically and out of sheer desperation and sick of pulling my hair out trying to get my AP stuff to work on the mac, ie: my Orion mini guider, my EQ5, stacking and processing pre-photoshop etc. I realise that I've got to bite the bullet and buy a PC laptop.
As a trial, I borrowed one from a mate to run my scope, guider etc . And its working, sort of - and I have never used Windows at all. But gee by comparison, it's soooo clunky and so not user friendly to operate, what the?! Ok that's probably an exaggeration but it seems so backward and fussy trying to do the simplest things, compared to using the mac.
But I'll accept that's probably just me and my struggle with the transition from mac to PC.
Maybe windows 8 will be easier?
Interesting debate, I'll apologise in advance if I've offended any PC diehards,
