Interesting.
One thing i was recently searching for - automatic disconnector script or similar thing... anyone knows, is there anything similar?

I tried to search for osso-wlan dbus interfaces but did not find much documentation... ie in Ubuntu, you can do a script, which can disconnect wlan using networkmanager after some idle time (say 5 minutes) - is it possible also with N900?
Polishing these kind of edges makes it really handy. click, check mail, click, done, and forget it.
Or then, why couldn't it go automatically to some *default* IMAP mail inbox, when you open mail application? Why do you have to to 2 clicks, to get there? etc...

It is already much better device than iPhone, why not make it *simple* too Waiting eagerly for next firmware release...
