New app choices have a habit of getting in the way of older favorites. Sometimes, a new approach or design can tempt you to give up one approach to solving a computing need by replacing it with another. That is the case with personal information manager apps.

For example, not too long ago I reviewed two workhorse PIMs called “qToDo List” and “Tasque.” It was tough enough deciding which one to use regularly.
