Set up for easy reading of webpages and has security second to none. Also, merges BB 10 OS with a sandbox to run Android and not affect the phone. Blackberry 10 is a far superior OS, but greatly lacking apps, so the Android box is helpful. Plus you get Blackberry hub which allows you to navigate the phone very quickly and in an organized fashion. (Also--battery lasts a full 2 days even on heavy use).
