I'm sorry to hear that Norm. These are things I never thought about at all, I just expected to download and have things magically work, a lovely, mystifying experience. Well, mysterious and tedious are getting mixed up!
I don't give a hoot about Bezos's foibles, I just wanna read a book <g>.
I guess I'll flail around with this, and see how the Sonys are programmed and consider them. Then, when I have a clue about MY eReader idiosyncracies, maybe I'll make a knowledgable decision. Who knows, maybe I'll get the new, smaller iPad next year, when (if ) it comes out.
Or maybe I 'll get used to the Kindle.
