I think I will try to deliver the major promised features before making any decisions with phasing out older OS versions.  That includes the library synchronization features and the annotations rework at a minimum.  Thanks everyone for providing feedback.

Rudy - I think any device that has MobileSheetsPro installed on it is considered an active install, but I haven't actually verified that. I probably should do that so I know how accurate the numbers from Google are.
