So... what bright future do you see for RIMM? I see none.
In addition, we have more than 50 salespeople and managers which were offered BlackBerries, and many have chosen either to turn it in or decline the offer with a BYOD instead. We are seeing lots of Androids and iPhones, so far I don't think any of the BYOD's are Blackberries.
What made all the difference for us was upgrading from Exchange 2000 to Exchange 2010. The iPhones and Androids no longer have to use IMAP; the calendaring functions are available now and the sync is very fast. There are fewer and fewer reasons to want to use the BlackBerry anymore for us. Remote wipe is one of them, although that does get murky with BYOD's and our relatively generous policies. With more critical mass on iPhone we will probably implement policies; I've tested adding VPN setup and alpha passcodes along with some other options and although it was a little cumbersome, the end result was easy to implement. Of course Android requires a different setup...
