Could Ubuntu overtake BlackBerry as the Mobile OS for Business

While i was watching the Engaget hands on (I watched TheVerge hands on too, just wanted to see more) with the new Ubuntu Mobile, at the end Mark Shuttleworth mentioned that since this is Ubuntu just with a different face on it, it can use and be controlled by the same Applications that are used with Ubuntu servers for Business. I don't know much about Ubuntu with business but it seems that Ubuntu is trying to step in while Blackberry is regrouping, and take the spot as the phone for business.
