This isn't true at all, back in the early nineties (and far on) a pc as a DAW hardly existed.3 – Very little software was available at the time
Terratec and Rebirth gave the start, but Protools was already market leader for years.
Photoshop started on mac, etc. etc.

Yet I remember you once being absolutely desperate about your pc.
Your exclamation at some point hit the problem exactly on his head:
'how can I even know if I have a software or a hardware problem??'...
a better description of the fundamental disadvantage of a pc can hardly be given.
Now you built a new pc system, this time you're knowledge payed off

But what would you have done at the time if you were in DTP business like you are now?
Thát is the question...
I still keep on saying that the choice for mac or pc is a matter of priorities (which is what you're saying also

Mony, satisfaction from building and selfcontroll to every inch, personal aversion against an OS or a company, whatever.
But of course I will also keep on saying the mac is the best solution for quality-ou-of-the-box and has the much better OS.
But you're still free to run Windows on a mac, even parallel to OSX...exactly, Windows as a window...
