Hmm yeah but I don't tend to read technical books on ereaders. Most of them require a bigger screen to be usable. I only read fiction on my kindle.

I haven't seen a good store that has the usual popular content without DRM. Well except on paper of course :)

But yeah I didn't know that existed for tech books. In fact the ones I bought online were from big publishers and quite expensive compared to fiction books. But perhaps that's just my niche.
