I think this is a great idea for RIM, but I think they were under pressure due to the competition hardware being somewhat superior to their hardware. Also with RIM losing ground on the tablet front, this move would solidify their position on the marketing front.

I can hardly see any other company, other than Google making a play for management. RIM have been doing this for years, have the infrastructure already in place, and have a wide range of clients who would hesitate (I sure would!) to migrate over to any other company for management solutions. Can you imagine Apple trying to set up their own management solutions? They already have a hard time fixing the calendar problems on their own phones, and with Apple's reputation, they wouldn't settle for management... they'd rather take ownership!

I think this is a wise move for RIM, and can only see them growing stronger in the business world should they pull this off without a meltdown!
