I too am a BES Admin for 2400 BB users and 138 PlayBooks. When we first allowed iPhone into our environment, BB #'s dropped to 1900 within weeks. Since then BB #'s have cmbed back to 2300 over the last three months. The story at my work is that those who went to iOS did so for 'fun' but soon learned that the iPhone was not a business friendly device and it cost them on average 30-40% more to operate. I expect when BB10 come out, the majority of those who went to iPhone will come back.
