So far am loving it, all apps actually work like they should :-)
My only concerns so far.
1. The hub is not really like in BB10, it has this Android feel, which I HATE. The "view" is so not BB10.
2. The keyboard is really small, not comfortable to type on.
Overall, I am very happy, I do think they will fix these things, need to give them some time. battery is AMAZING, virtual keyboard is amazing, like on the Z30.
Remember to update all BB apps right away, it comes with a REALLY outdated version of hub and the rest.
