i dont know about all of you but i dont like spending money if i dont have to . so heres my free work around.

export your now calendar to a text file
open palms free desktop calendar program
import your text file to the calendar.
export the calendar as a ical format (vcal)
go into your palm preference folder and delete the user file so next time you have a blank calendar
open ical and make a new untitled calendar and import your file.
when you next do an import you need to delete the untitled calendar in ical and then make a new one over again

its a pain in the ass but it works

or just start using ical because your tired of doing the workaround and waiting for a program that is never going to go to market.
