(Disclaimer: I really like the N800! Yet, I’m going to collect a few minor nits about Maemo and the N800 in this little series…)
Maemo comes with a central account settings controlpanel, but it’s not that central, actually: It only contains the Jabber settings. The Mail client has its own account settings menu. Both account settings are found through completely different menu paths on the device and it’s not very obvious where to look when you want to create or change one of your accounts.
It would be nicer if accounts for all online applications such as Jabber and Mail were stored in the control panel.
