I've just switched to blackberry
After years of playing with different smart phones and always going back to my old S40 Nokia I ended up with a BB Q10 and they do most things right. I used the phone for a week without ever signing up for an account with them and the hardware is happy to talk to my servers and my cloud. The only issues were that it had some trouble importing a few bizarre contacts, its IPv6 doesn't work with my home wifi router, and it can't use just DAV for its calendars and needs CalDAV. It did take some tweaking to the notifications since its default mode is "sleep mode is off mode" which is isn't the best someone on call 24x7. Its permissions for apps is much better too as you don't need to hack the thing to tell it "this app doesn't get that permission". The sand boxing seems to work very well too for both BB and Android apps. I like the real keyboard on a device that was just about as large as I'm willing to carry around.
