The key difference between Windows Phone and Blackberry is that no one has really heard about Windows Phone (surprising, I know), but people clearly have a negative perception of Blackberry. The latter is far harder to correct than the former.
That's not really true. Windows Mobile wasn't as widespread as Blackberry at its peak, but a decent amount of people had it (and hated it). Just last week I was trying to convince someone that Windows Phone really was something completely different from her old HTC Tilt.
