Are you saying people rely/depend on their business backbone to iOS or Mac OS or any Apple OS?
Sorry to say but Apple is a consumer grade product, not military spec or business grade.
All gibberish. There's room for both, but stop pretending Enterprise is all server racks and desktop Windows workstations. More and more companies give their employees iDevices so they can count on the security of iOS and provide thoughtful ways to access real information.
There will always be room for the Dell PowerEdge and other servers, but the idea that Apple has no Enterprise penetration is shortsighted.
