Agree, but MS is pushing a lot of work and concern onto people who paid to use their software just so MS can sell advertising and provide potential opportunities for hackers. Group Policy and dedicated, informed, and vigilant employees to the rescue while companies indirectly subsidize MS marketing efforts well beyond the amount paid for the software.
In the enterprise, things are a bit different, and perhaps more controlled and consistent -- again, Group policies with regards to information disclosure, etc.. are perhaps more restrictive in nature. And those use cases can go from Points of Sale to Call Center/Support operations to Road Warriors to Engineers/Developers - a POS terminal, obviously, that needs to be locked down very tightly for multiple reasons, not just for PCI compliance...
That's probably why it'll be some time before we see deployment into the enterprise space - many companies are still on Win7, and the only reason why there is that WinXP was basically end-of-life.
It makes me wonder ... is this the golden ticket for Windows Server consultants. Imagine the sales pitch ... Hire us to make sure your servers are not impacted by MS views about information sharing on your network. Then keep us coming back to make sure they are not impacted by any changes MS made while your attention was directed at running your business.
In many ways this isn't much more of a challenge that supporting BYOD - and Active Directory and knowledgeable NT SysAdmins have been doing this for some time now.
If Google were to develop an enterprise Android, would you ask your employer to migrate to it?
Highly doubt it - Android was never designed with security as a key priority - which makes enterprise deployments a major challenge - folks can try to add it in later, but it's just such a huge threat surface, and with the blackhats beating on it on a constant basis...
ChromeOS on the other had - it's reasonably secure, and security and sandboxing was designed in from the very beginning - as such, I could see it being deployed in certain use cases, but not as a general migration..
AD and Win will be around for a long, long time - not because it's better, but because of long term investment in the support infrastructure and ecosystem, esp. for Productivity and Business apps - and many shops are also steeply invested in MS Developer Tools, which, again, is another lock-in to the Windows platform.
