Some alternative thoughts on the Gartner predictions-

#1Twenty percent of BYOD projects will fail by 2016 due to IT’s “heavy hand.”
-Many companies today practice a lockdown strategy-no admin rights, for in general the ability to have a more controlled environment, essentially for their process of updating workstations. This should be blown up with a "BYOD" strategy for corp owned assets--essentially give users rights to install software, with the caveat that the company policy is to reimage the device with a baseline image should issues arise. This would mirror the employee owned personal device "BYOD" , and in the end, improve employee productivity.

#2 Strict mobility policies will drive employees to want to isolate personal data from business data.
-The real concern here is the wipe of all personal data from a device without the user having any backup of it. Better to have a policy that enables wipe of the device, combined with a provided service to Box, Dropbox, etc that provides a backup strategy of the device so the user isn't petrified to lose all their personal contact data, photos, etc.

#3 Mobile browsers will gain market share for app delivery for multiple platforms, and the role of HTML5 in solving issues that arise with the multiple platform problem
-I think the concept of an in house/enterprise app store is good, but is it core or context to your organization? if they are just users of a service, and not actively developing the service, I would classify this as context-something you should NOT do , and rather find ways to intelligently redirect your users to the Apple/Android app stores, and not spend your resources here.
