I am now(-ish) the proud owner of an Amazon Kindle with WiFi and 3g.
After having used it for reading 1,5 sci-fi novels, I must say I think it works.
One problem is of course the complete lack of Norwegian content. Maybe someone in the oh-not-so-innovative publishing industry should look into that.
A tip for getting the classics is to download them from http://www.feedbooks.com/help/kindle instead of buying them from Amazon.
