Finally,BORG is a program that operates like most PIM's. It is a tool that can successfully track tasks and calendar items. My favorite part of this program is the ability to track sub-tasks within a task. BORG allows a very detailed task view you don't find often in PIM's. This makes this program excellent for independent contractors, freelancers, academics, and small businesses. BORG also offers the ability to track all changes to tasks. While this program is the last on this list, it certainly shouldn't be overlooked.
