The bb10 user base is a bit more difficult to calculate. If we assume that 80% of those 10 million were using bb10 as their primary device, we would suspect that half of those are still using bb10 today - that leaves us with about 4 million. Add back about a million devices that were sold since then, and that would leave us with about 5 million users today.
Pushing out the posts at each end to increase our confidence, we probably have somewhere between 5 and 10 million total Blackberry users (bb10+bbos) today.
