Realise this threads a few days old but I've been experiencing the same thing - ideally I'd like all my calendars to be stored in one place - Google Calendars. So I linked my google calendar to my facebook account (which for a lot of the items it just says "busy" for instead of the actual item but hey). However either the N900 doesn't import external events from Google Calendar or Google Calendar doesn't publish them via MfE.

Anyone had any thoughts on this?
