Thanks for all the replies, I really love this forum
I think I will dare to place an order. If one tries to wait till the industry figures out that this is the future and perhaps it's stupid to make the same mistakes as the music industry, one would have to wait a long time (sadly).
Anyhow, the important thing was to assure myself that it was possible to buy books from a place with both good selection and possibility to remove DRM. To actually do so will be a late problem.
Thanks for the help!
