That is complex because there are two article reasons! One is hard headed IT Managers complaining about Apple this or that. The second it would put out the current supplier and support don't know anything about/supporting Apple.
Plus economics have change businesses IT drastically! Says Microsoft has drastically changed the way Microsoft Server fees are being charged to businesses. Now most businesses went to Linux servers and now allow bring your computer. Microsoft is shooting themselves in the foot of Server fees!
I wasn't really posing a question as such, I know full well why Apple doesn't make a dent in the Enterprise. Microsoft and their partners have many excellent tools for managing PC's & servers. I manage over 70,000 PC's and around 10,000 servers using Microsoft tools and services. You can't really do much with a Mac.
Then there's applications, or lack of for a Mac. Most vendors show little interest in supporting OS X. It's dominated by Windows and this just isn't going to ever change.
Don't get me wrong, I love my Macs, but they simply have no real place in the Enterprise.
Most businesses are not moving to Linux. There are far more Linux tools and appliences available which have replaced some Windows Servers, but with the adoption of cloud computing, centralisation & virtualization, Windows Server is as healthy as it's ever been.
