hey even if you do the homework! Before buying my n900 I red everything that had been published online, and still no reviews or any pre-users commented on the PIM other than it didn't sport categories.

if you visit Nokias marketing site it lists full PIM function http://maemo.nokia.com/n900/specifications/ (and i think it is reasonable to presume it will be at least on par with a S40 phone.)

visit http://maemo.nokia.com/features/calendar/ and they tell you it syncs and it supports tasks (but it docent support tasks, every pda or phone made to date that sports tasks, sports the name and the description, it just the n900 that only supports task names.)

but had anyone made a note about the limited PIM I would have held off until palm made a GSM phone with an auto focus camera, or Nokia added, PIM search and Task descriptions.
