I think we both already agreed that an open format is probably better/safer than a closed one, and that drm is no good, in any digital stuff, not only books. I only got the feeling that I'm quite a bit more concerned (and paranoid, even) about this stuff than you and most others are. I've learned about the format wars the hard way, in the past.

Btw: Tried the Latex thing already. Html to Latex does not convert well. Latex to Html can work very well. Latex to epub is bad, using the conversion utility Pandoc, for example. Latex to Html to epub yields a usable result that needs to be adjusted. If the book is not too big, creating the epub file from a plain text file yourself is faster. Converting from epub to mobi works well, as we all know.

In the end I thinkin I'll be going with de-drm'ed epub, as it's the easiest format to take apart, and therefore probably the best source to convert into other formats.

I'll have to try and see if an Amazon azw, or mobi, converted to epub is understandable when you take a look inside.... I'll convert an epub I made myself to mobi and back, and see what comes out.
