There are several things about the Palm pim to take note of.
An obvious one is that with Palm Calendar you can set bi-weekly events, in fact almost any strange combo:
- Daily until..
- Every week
- Every other week
- Every month
- Every year,
- Every N day(s) until date (or none)
- Every N week(s) until date (or none), on day X
- Every N month(s) until date (or none), the Xth of every month (e.g. the 27th)
- Every N month(s) until date (or none), e.g. the 4th Thursday of that month
- Every N year(s), until date (or none), e.g. November 27th every year.

Another point about Palm PIM is that everything can be done without wading through menus or selections. According to popular lore Palm had a guy who's full time job was to check and make sure that nothing would take more than 3 clicks.
