So in trying to decide which program will become my personal information manager I've downloaded Yojimbo, SOHO Notes, Mori, Circus Ponies Notebook, and Formation. Formation seems to be the most full featured application I tested, however it also has the steepest learning curve. It can do whatever you need it to do, be it orginize your contacts, calender, passwords, serial numbers, etc, etc. But to me, where my needs are modest, the program seems a bit overkill. Plus if it's true that the developer is no longer writting programs for the Mac, then support may become spotty, which is unfortunate. Yojimbo is on the other hand VERY simple to use (almost to a fault) and syncs with dot Mac which is nice. SOHO notes is another alternative, but support for it is also spotty.
