Datebook 6 was released today! I haven't purchased it yet, but when I do, I'll upgrade this description. Here's what's new:

Not as revolutionary as I might have hoped, but the "today" screen looks interesting and the to-do sorting sounds like it might be useful for somebody like me with hundreds of to-dos.

i don't know how anyone who has a PalmOS device (treo or zire, etc) lives without this one - i'd never go back to the bundled calendar that Palm Inc. sends with the device. DateBk6 is powerful and easy to use - so many options that allow you to personalize your calendar to fit the way you need to use it. I use the "float" option for things that i need to do that aren't date specific, etc. Well worth the money and worth checking out. It makes keeping up with my schedule an easy task instead of a frustrating one. (via joe)
