Some citys (even at Finland) there is Wlan city network where you can connect and some cafe shops and hamburgerbars also have wifi for customers. I almost forgot Assembly computer demo party.. Party network is full of hackers..

I know that pc(windows) is totally unsafe if there is no firewall.. But I guess that Linux is not totally safe either, if its not configured correct and these days firewall is important.

If someone has network connection for N800 that has no firewall. It would be very intresting test this..
