I'm pretty sure Microsoft is a pretty big player in Enterprise SaaS already.
They are, but that's also the market where their lock-in has least effect.
Apple is good at the monetization angle of this. There's no reason Microsoft couldn't do the same (except with software, not hardware).
Example: 90% of the time I'm on a webex/gotomeeting, I'm looking at one of three things: 1) Powerpoint, 2) Excel/Word or 3) a Browser.
Why can't Microsoft make that kind of sharing easier? My guess is that they were too arrogant to make things work for the folks not on the latest versions, or on different OS's.
It's 2014, that's not good enough. People expect your product to be sociable and flexible. And that's why it's Cisco/Citrix software that's showing the MS docs.
