For many years I was an early adopter and have fallen repeatedly on the nose. That's why I was quite skeptical and cautious after many iPhones, Androids and Sony. I also wanted to have back buttons because my virtual keyboards are not fit - no matter which system. The Q10 I bought used and it has fully convinced me. The Tastaur combined with incredibly good word prediction let me write half novels. The display is crisp sharp, but has a few levels of brightness. The operating system BB10 is a real pleasure with the swipe gestures. All data (also on the 64GB memory card) are encrypted. The integration of WhatsApp, Facebook and Dropbox are rudimentary but available. The AppStore is hard to use, but there is the timetable of Deutsche Bahn, so I'm satisfied. The battery life is okay, but not outstanding. The reception is only just okay, but the voice quality is excellent. The browser is excellent, there is also a full Flash support, so that really every video can be played. So if you do not emphasis on games and tons of apps, but work with the mobile phone and want to do what, who can not get on the unit.
