Abstract: Apple is making boatloads of money selling stuff to people. Reconfiguring the company into an enterprise services firm is an unacceptable risk.
'Waaaay back in the day, I was invited to an Apple roadmap presentation for the various big Mac users in the greater LA area (mainly aerospace corps). Dating myself, the main heads up was the upcoming Mac IIfx. The current sealed lips paradigm wasn't always graven in stone.
But, that was before Windows 95 almost ate Apple's lunch, and Macs got kicked to the curb across "the enterprise"... almost simultaneously across North America. Almost as quickly, the ecosystem of Mac-related enterprise solution vendors ditched the platform. When Jobs returned to refocus the company's direction, the focus was on what he had left to work with: consumers (with bones thrown to graphics/video/audio pros). You could see this in his original product mix: iMac, iBook, the restyled G4 mini-towers, and eventually the iPod.
This ended up working so well that quite a few consumers really wanted to haul their Apple gear back to the enterprise... which is how Apple first got there, one MacPlus at a time. Now, with the iPhones and Pads, people aren't just sneaking their toys in, they're putting in purchase orders, and the IT departments are forced to adjust.
It's not completely unreasonable for them to ask Apple to rework their products to make this a bit easier. It may happen, but I wouldn't hold my breath: Apple isn't equipped to service the enterprise, and doesn't want to spend the money to make it happen. The boys and girls in Cupertino would need to spend tens, perhaps hundreds of millions of dollars to set up the hardware/software/people infrastructure - more or less from scratch - to provide reasonable enterprise marketing and support.
And why? There's not all that much profit in selling to the enterprise, except in services. Virtually *all* of the non-Asian computer vendors have reconfigured themselves into enterprise services companies that just happened to sell some hardware/software for them to integrate, and the Asian companies are on the same path.
Apple, meanwhile, is making a boatload of money selling hardware/software to people. There is plenty of foreseeable risk and little known upside to reengineering themselves into the likes of IBM/HP/Dell.
