My concern is that the N900 is designed to be always connected and it is a Linux system with all the standard security issues. It probably comes with a default root password with lots of open ports. Are users directed to change the root password? Or do users have to know that to do to protect their device?

Anyone reading this is not a typical user. The typical user takes the 'phone' out of the box, puts the SIM in, powers up, and uses it. Security hygiene is not on their radar.

Since this device is different from the previous tablets from Nokia does anyone know what is provided to protect users from the nasties of the world?
