This is the sort of thing I badly want in my life, but the sad reality is that Amazon has a massive ~monopoly~ grip on most of the e publishing market. Most of the books I want to buy only have a electronic version for Kindle.

Being able to strip the DRM so I can read on non-Kindle devices is a major cat and mouse game and it's majorly frustrating to have a solution worked out only to have it break the next time I buy a book. Has anybody had continuing success with this?
