Most Linux distributions, unlike OpenSuSE, OS X and Windows, do not have a DNS Cache service installed by default. Your computer will need to lookup a website’s IP address every time you visit it.

It can take a ‘long’ time if your using a slow Internet connection (or a wireless LAN).

The Danish language makes use of two letters [åÅ] and [øØ] which are not on my Icelandic keyboard. Having to switch permanently between keyboard layouts all the time with key combinations (Windows way of doing things) such as alt+shift is tiresome! It turns out that there’s a very easy way to switch between layout in GNOME.
