Have been using Priorities for several years now where it has lived on my home screen from day one. Love the simplicity and clean interface. Provides the functionality I need and set up so it integrates directly into a Gmail calendar for viewing on every device. Use it to track bills due, work items, Groupon/LivingSocial due dates. No reason to look elsewhere… A couple of suggestions for enhancements to increase usefulness — 1) integration to the Notification Window with a widget showing items due and ability to check when complete and 2) Ability to tie individual lists to separate calendars — i.e., Work tasks, Finance tasks, Personal tasks. etc.
