Who are the Linux users then??
BTW, I have built well over five hundred Intel based PCs, with various Winbloze flavors on them, and have sold way more than a million bucks worth of HW at the WHOLESALE level. That means that the questions given me by MY customers, were from the CONSULTANTS.
Strangely enough, they always took my advice, despite my being a Mac user.
engineers and libertarians, mostly. Nowadays, no one needs to waste the bandwidth on OS fundamentalism, unless they're truly in need of a life. Cheese Louise. Apple's painted itself into a nice little corner with its closed, proprietary system 'for the rest of us.' No problem. Y'all have yourselves a field day.
But when I want a scalable, enterprise strength platform, it's going to be either Wintel, or something with dual MIPS cores running whatever RTOS and/or Unix variant the work demands.
When I want an industrial strength database engine, guess where I'm goingto look - it won't be in Apple's direction, that's for sure.
For a real rubber-meets-the-road experience, check out data center infrastructures. Go visit your local ISP. Apple's MIA, and rightly so, 'cause it doesn't have the stuff.
Moral of the Story: pick the right tool for the job, and don't expect a toy to do an industrial tool's job....
