I have been using the US international keyboard both at home and at work. It is a blessing so that I don't have to change keyboard layouts when changing languages, since it provides grave and acute accents (e.g. for French), the double s German letter and umlauts, euro symbol, etc. and also plays nice with programming languages and UNIX shell: for instance, quick access to slash, curly and square brackets with the same modifier key, backticks without modifier keys. Another advantage is that the layout is the same as the US keyboard you are already used to, just that some keys have new effects.
