As posted in the Maemo forums (http://talk.maemo.org/showthread.php?t=35136), Google sync is not supported yet and causing problems for many people. I don't currently own the N900 (not yet at least ;)). This is a very important feature for me (and I am sure for many other people too) and I would seriously consider not buying the device if I could not sync my nokia address book with google contacts... Is this issue being worked on by Google or Nokia?
