Al Sacco posted this interesting Pie char that breaks up the number of users that currently have BlackBerry OS 5.0 installed on their devices and those that don’t have it installed on. Only 20% of BlackBerry users have BlackBerry OS 5.0 installed which is about 8 million out of 41 million users. 24% of BlackBerry users are running BlackBerry OS 4.6.1, and 27% are using 4.5.0. These numbers are kind of odd consider how much better OS 5.0 is compared to 4.5.1 and 4.5.0. It makes me wonder why a lot of users haven’t updated their device . Is it because a lot of BlackBerry owners don’t know how to update their OS? There are also folks out their that don’t care about updating their OS because they are fine with what they currently have and don’t want to have to learn a new OS . I wonder if a lot of these users are 8330 users because I don’t believe they have every gotten an official OS 5.0 update (someone check me on that) and if that is the case then 8330 owners make up a good number of the BlackBerry users around North America and the world considering that the 8330 series is the most popular device. What BlackBerry OS are you running and why? Leave it in the comments section.
