But an internet usage-based survey found a slight BB market share increase in the last month.
This would be an expected causal effect with additional BB10 users, since that OS is more web based over BB7. Still, surveys are showing that Blackberry market share is so small now, that it may not even be included in future surveys as it is less than 0.5%. It will simply be 'lumped' in with the 'other' category (think Symbian and Palm), until Blackberry mobile dies.
