For those who use palms, there is a new version of Agendus out. It has many spiffy features, most of which work. The one I like the best is a checklist feature. You list items, one per line, in the notes section, with a + or - at the beginning. This displays as a checklist in a view of the item, which can be checked off on the display. Cute, kind of wiki-like. Many other little features tucked in too. As we have come to expect from Iambic, there are also bugs and inconsistent behavior. Selecting the monthly list view crashes my TX every time.
It's interesting to me how Datebk and Agendus have diverged. Datebk still seems like a big old truck: pretty reliable, lots of knobs and dials, but no fun to drive. Agendus wants to be a luxury car, but it's in the shop a lot, the engine (400 MHz Palm) is a little underpowered for some of the features.
