[quotemsg=11475389,0,5190]House70: You can download your library at any time onto any device which has Kindle software - which is basically all platforms. Although I would also like to have an SD card slot, it just isn't all that necessary. 2GB stores a TON of books, and you have access to your all your other archived books via Amazon's Cloud. What you call copyright paranoia, many call convenience and safety. If my device is stolen or destroyed, I can just redownload everything seamlessly via Amazon. It's really no different from what Google does.
If this was a smartphone or tablet, and I want to store a bunch of movies, music, games, etc locally for speed/bandwidth purposes then of course SD cards rule. My tablet and phone both have 32GB microSD cards installed. But I have found that with my singular-purpose Kindle e-reader, I just don't need an SD card.[/quotemsg]
Fortunately, I am the kind that likes to have control over what I have purchased, in this case, books. I have plenty of books that are not from Amazon, and I have books from Amazon. If my device is destroyed I can always get my books back from my PC where they're saved on a drive, and copy the whole library on the SD card., as opposed to waiting for the downloads. To me, convenience is having access to my library without needing to be online for that.
Also, what happens when Amazon gets in a pi$$ing contest with an author/another publisher or some other entity over distribution rights? They can always pull the book(s) from the library, and voila! Puff, it's gone from yours as well. Remember "1984" debacle (I believe it was that book)? It can always happen again.
