Today UPS delivered my GDIUM!
I am writing this blog on it!
First obstacle to overcome was finding an adapter for the electrical outlet. Once this overcome, gdium started nicely, asked me some questions about language, date, etc.
It however failed the "first login" to gdium.com. Dunno whether it is of wrong username/password. Could however access without problems other web sites like www.nzz.ch. After an exit from the firefox, the initial install process continued and I the GDIUM rebootet without any problem.
