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."
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.
