Security, Reliability and Market share
This is a conversation I have been waiting over a year to happen.
To make a successful hybrid of business and personal data and devices segmentation and proper authoritative control is a key element. I give a standing ovation (of one, me at least) to Google for actually starting the development of the key controls in this element that has actually been needed for decades. (yeah, laptops needed it but never got it back in the day) I see this as a core "feature" technology mechanism that will be taken for granted within the next five years.
So what should this really look like from a use-case point of view. I believe that enterprise IT needs the authority and immediate ability to protect the corporate intellectual property (and devices) through the tools of absolute policy control and ability to "scrub" a remote data island, but only for what belongs to the company. The IT department needs these tools to fulfill it's part of the mission in protecting corporate assets while meeting the desires of the social mission in allowing personally owned and customized technology for user convenience. (BYOD is a much abused meaningless catch-phrase, please quit using it)
Creating the built in separation of business and personal gives IT a standardized mechanism that we have have had to customize and crowbar wedge into devices before or just blanket take ownership and responsibility for the entire device.
So why is Blackberry upset? They have reliability issues due to the design of having everything go through their data-center. This channel has failed more than once. Lesson learned, single point of failure bad. The android mechanism provides a mechanism to "privatize" the key data synchronization into each enterprise's IT department or spread out the load across the massive Google data center architecture. This means much lower risk as a platform, and lower isolated failures (if a company has a server go down, no one else's businesses are affected) Versus, Every single hand-held in the market experiencing an outage of sync data because Blackberry data service centers are getting DDOS attacks.
Yet if I was Blackberry, I would be nervous too; but rather than whining, I would look to learn from Google and build upon it.
