Keeping up to date with multiple calendars, tons of information and never-ending to-do lists can pose Herculean challenges if one doesn't have a proper set of tools. An effective way to solve that problem is with a well-oiled personal information manager. However, it is not always easy to find a PIM that gives a useful set of components to handle diverse needs. I've tried PC-based solutions, mobile phone calendar and note-taking apps, as well as Web-based products like Google Calendar augmented with Web-browser note gadgets.
