I was wondering about that as well. I am pretty sure that almost all the time after the iPhone's launch to the after-effects of the burning platform memo, the actual smartphone world leader was Nokia. The E-series was the business phone of choice at least here in Europe, and I still have never seen a Blackberry in my life.
I never understood why BB was so popular in the US with their weird infrastructure choices. Nokia's phones integrated straight into your corporate networking infrastructure via VPNs and did proper email without there being any middleman servers. I guess the US phone network infrastructure was just simply so bad back in the day that special solutions were required?
