I was a Palm user for many years and find I can work with N810 as my PDA. I installed mCalendar which syncs properly with Google Calendar. I'm a Gmail user and the N810 mail package easily interfaces to Gmail with IMAP. Contacts is the week link as it has no place for addresses or notes. I also installed notecase so I could keep private information encrypted. Maemo mapper can use the excellent Google street maps. On balance the N810 is superior to the Palm whose days are numbered.
