I agree that supporting lit is not be the best way to support "less closed" formats, although it's true that what I meant was crackeable formats, as well as any other DRM-free formats.
Something I can think of, is to buy the currently crackeable format. In that way, the books you buy will be available forever, in any format you choose.
But, what if the book you want is not available in a such format? Or, what if there are no currently crackeable formats?
In the end, it all comes down to your personal decision. What you need is information to balance all the factors involved: price, portability, reselling/lending feasibility, etc.
All formats have their tradeoffs and it's hard to say which one is the more reasonable.
In any case, I see everyone would agree that digital content protection still has a long way to go.
