My Android phone is a BlackBerry Key2 and I've loved it for the almost five years I've had it now. I have trouble living without a physical keyboard on the device and I lament the fact that I may have to carry a touchscreen-only phone for work in the near future. I don't want to carry two, but I may end up doing that anyway.

The Key2 is easily the best smartphone I have had, beating even the Nokia N900 due to reliability (i did not get five solid years out of that) and compatibility with mainstream (read: Android) apps.

(Compatibility is not perfect, though. You may think android is android but the screen of the Key2 is a few pixels shorter than the common ones, so some apps have buttons that are always rendered outside the screen. Also some apps seem to do some sort of vendor check against a whitelist that does not contain this model.)
