Changewave's latest report gives some very interesting numbers for the iPhone in the business market:

1. Apple is the number two manufacturer in the planned purchases category (ahead of Nokia (this must be US-centric), Palm, Samsung and Motorola) and already has 5% of the business market. 
2. Apple leads (59%) the very satisfied category in their survey by double digit numbers and kills Palm and Windows Mobile devices (10-30% very satisfied).
3. While RIM currently is the market leader by huge numbers, its recent outages and declining satisfaction ratings are leaving a big question mark in the business landscape - one that Apple is hoping to exploit.

All of this makes the March 6th event, which promises some enterprise announcements, all that more exciting for Apple and its (future?) customers.
