Pro Gesture control
Balanced between the fluidity of iOS and features of Android, BB10 represents a good user experience with the use of gestures that permit rapid access to key applications such as Hub.
Pro Meeting mode
Meeting mode automatically silences your phone when the calendar indicates you are in a meeting.
Con Possible discontinuation of support
RIM has recently started to shift its focus to releasing hardware running Android. If it takes off (or at least drives higher sales) BBOS may get less attention or discontinued altogether.
Con Limited selection of good apps
The Blackberry OS has very few apps actually designed for the OS. Depending on your uses this may be problematic, however the ability to save web page links to launch from the app list mitigates this somewhat.
