Despite OS 5.0 being released over 3 months ago, 26.6% of 9530 users are still using OS 4.7. While OS 5.0 use has increased over time, the 73.4% that use it now are not that much more than the 61% that used it the first month after release. Most users either upgraded right away, but those that didn’t are unlikely to upgrade at all. Given the many improvements in OS 5.0 everyone should switch, but a surprisingly large number have not.
This data comes from the users who have download the popular free Pixelated game from BlackBerry App World in the given month. Pixelated does not report back at all, so statistics are taken via App World at the time of download. Statistics are from the 9530 model only in order to create some consistency across the data, especially given that almost all 9530 users are on the same network (Verizon). Pixelated had already been available for the Storm for a few months before November so these numbers are not skewed towards early adapters, but neither are the numbers skewed towards those that have little use for their phones, as this population has still gone and downloaded a third party application. Data from the beginning of the month and the end of the month were treated the same.
The above graphs were made from the data I collected, with the most relevant being the recent month of January.
