On: Ask HN: can I transfer a $6,000 Kindle book onto PC, DRM-free?

But really... There are other ebook readers besides the kindle..

iRex let you use open formats, and the software is also opensource and in continuous development: http://www.irextechnologies.com/

A lot of the Kindle's source is Open Source as well, under a GPL license. http://www.amazon.com/gp/help/customer/display.html?ie=UTF8&...
