What can Windows do that mac can't? Because I can guarantee you that the list of things Mac can't do that Windows can is MUCH MUCH longer. So unless I am bereft of common sense, I'll be sticking to Windows
Is this the point?, No, the target demographic here is Blackhatworld memebers, which i can garuntee to you is a large majority of window users, you know how many people here are from India(for example, and many other countries where Mac's aren't so common, i.e not the US, which still have what, under 50% Penetration there too?)? You think Macs are common there?.
And thats not true at all from a programmatic point of view, developing for Mac unless you're developing on Objective C isn't so different from developing to any platform, all the bells and whistles of the UI are just bells and whistles, and you can get not too far from that with Compiz on Linux, Programmatically and functionally speaking, there is ZERO difference from him, except he'll just be targeting his code for Mac, so he'll write it with Mac Libraries/API's instead of Win32, thats IT.
Edit:I thought your saying the opposite, ignore pretty much everything, but my points still stands for any Mac fanboy who wants to argue this as his claim.
