My take on this non-issue is: I won't buy any ebook I cant de-DRM. Doesn't mean I'm doing it; so far I've had no need. But I want that option. I'll not be a lock-in slave to any DRM scheme. Lock-in to Adobe (or Apple) is no different than Lock-in to Amazon. I'll not surrender my future buying choices to anybody.

I also backup every ebook I buy (the DRM-free majority as well as the handful of DRM'ed ones), assuming that at some point redownload will go away. Just a precaution.

The real question about DRM flavors isn't about DRM at all, but rather which bookstore(s) will you be buying your books from. If you find Amazon's catalog and storefront compelling you'll be buying from them and loving it. If it isn't, you're stuck with the Adobe backed camp; lots of choices, all offering essentially the same catalog at the same prices.

And, of course, the either/or choice only applies if you're not deDRM-armed.
Having DRM-stripping as an option breaks the choice back to more reasonable terms: is it a good book? Is the price fair? Does it fit my budget?
You won't care what format it comes in or which store sells it.
It is a liberating tool to have even if you don't use it.

Worth looking into, folks.
Just as a precaution.
