So does anyone know of another online bookstore that is completely DRM-free? I mean both hard DRM (encryption) and soft DRM (watermarking, be it visible or invisible). That O'Reilly was completely DRM-free (AFAICT) made me spend quite an amount of money on their eBooks over the years... I wonder who wants to serve that market in the future? It seems that all the other options at least do watermarking, which makes it uninteresting to me.

Guess I'll have to buy everything as print books again...
