Look at it from a Windows System Admin perspective. You want WP7 to be the phone OS because you are assured Microsoft will bring out tools for Windows 2008 to admin the phones. You can probably get another certification and you don't have to deal with Apple or Google. You can keep your full Windows stack and don't have to worry about something new. Blackberry was OK, but Apple and Google are not exactly a good thing.
I think this kind of thinking is at the root of Microsoft's current problems. When they held 95% market share they could afford to be this insular but they just don't seem to know how to maneuver in a heterogenous world.
I'm really not talking about Microsoft the company. I am pointing out a lot of people have their wagon hitched to Microsoft and make quite good livings in the current IT world.
But the enterprise-wide idea only works if "the powers that be" are ready to insist that all company phones are Windows too. Just a few iPads and iPhones here and there in the executive suite makes the Microsoft-must-be-everywhere argument look like an uphill battle.
Yeah, I am not saying anything different. If Windows phone market share keeps dropping, then all of the old arguments that kept other desktop OSes out don't work in the smart phone game.
