Samsung's Knox Platform is likely going to bring a lot more competition to bear, particularly now that Google has partnered closely with them - so things are certainly going to heat up soon.
Does that mean 90%+ issue Apple devices to some employees? Or simply support (or tolerate? Or turn a blind eye to?) using them on the corporate network and/or corp email? Or something in between?
Corporates tend(ed) to use Blackberry for their management / key people. Those people tend to use Apple and Android for personal use.
(Big) Corporates tend to use IBM for data intensive / traditional mainframe roles (transaction processing, etc). Big ticket stuff.
(Big) Corporates tend to use Exchange. Great chance to cross-sell a now internal product, Blackberry, which was already approved by information security obsessive corporates. But Blackberry is unpopular, BBN its only selling point.
IBM now say 'Apple is OK too, we trust them'. Said executives now demand an iPhone / iPad app, which in reality was already developed 2-4 years ago, but only distributed to people in information security / in-the-know because they really wanted it and could get it. As Apple can now be cross-approved on the same terms as IBM, vendor approval is easy.
Not release a cooperation agreement, but this has been in the works for several years. Apple gain a lot. Not sure what IBM gain... perhaps cloud agreements with Apple? Perhaps support agreements, perhaps something much bigger?
"The Good Dynamics Secure Mobility Platform currently manages iOS, Android and Window Phone devices, so these are the only platforms included in the report. BlackBerrys, for example, are managed via BlackBerry Enterprise Service/Server (BES) or directly via Microsoft Exchange; as such, they're not represented in Good's report."
"Talking specifically about tablet activations, iPads made up 91.4 percent of all activations, while Android represented just 8.6 percent of tablets activated by customers."
Apple has already been doing a lot of work over the last couple of years geared towards making iOS more acceptable to enterprise and we're clearly going to see even more progress in that direction.
Say what you will about the quality of IBM's software and services, IBM probably understands enterprise-scale IT better than anyone else. A lot of that knowledge is now going to be transferred to Apple, as iOS and the related infrastructure is brought up to the standard that IBM clients will demand for this to work.
In those areas, and many other corporate enterprise areas, Apple is on is already on its way out, specifically because they never really integrated or put any special effort on integrating with the existing corporate infrastructure.
Meanwhile, Microsoft has used this time that Apple squandered to finally catch up for the most part.
A lot of large corporations gave Apple a chance 5 years ago and nothing ever really came of it. They will not be getting another chance any time soon.
