Today, January 30, marks the four year anniversary of BlackBerry 10. While not an anniversary usually 'celebrated', like 5th or 10th anniversary, we still wanted to go ahead and recognize the date so put together a quick video taking a look back at most of the devices released with BlackBerry 10. If you're really looking for a trip down memory lane, and to get a closer look at the events that took place on launch day, then I suggest taking a look at this article from 2014 as well as our BlackBerry 10 launch roundup.
