Ah, yes, I forgot about that nasty little detail of ebooks through vendors/with DRM are basically rented rather than purchased. Grrr.

Word to your last paragraph - it's not a replacement, it's a supplement, it's a widening of the way, and people who want to go with one format only strike me as exceedingly narrow-minded.

Maybe e-reader folks will create a special waterproof case just for bath-readers...
