BB will fail at non-consumer level - here's why
Being a Bold 9700 user I waited until the Q10 was available to have it replaced. Alas corporate would not put it on their approved list due to concerns over:
1) the cost to upgrade the existing BES server to the version that is compatible with the Blackberry 10 operating system.
2) the long term viability of Blackberry as a business.
I even asked that the Q10 connect to the Corporate Exchange as an activesync device (same as the iphone) but they came back with "Our standard is iPhone, with no plans to add BB10 devices at this time."
