The concept of an e-reader is intriquing, and tempting. There are so many books available now that can be downloaded on an e-reader, and even older out of print ones like what is available at Project Gutenberg, http://www.gutenberg.org. The older needlework books available there have instructions and tips that aren't found in newer books, so getting them onto an e-reader is exciting.
Trying to decide which e-reader is hard. Amazon's Kindle doesn't allow you to save anything, like on an SD card, but the NOOK does. That one feature is what is influencing my decision on what to get. Also the NOOK uses E-Pub formats, which if I understand it, is a more common format for downloading books, whereas the Kindle has it's own format that can only be used by the Kindle, so if you wanted to buy a book from Barnes and Noble, you couldn't load it onto a Kindle, and vice-versa.
Kindle saves all of your purchases in your Amazon account, but if for some reason you have a dispute with Amazon, they can lock you out of your account and your Kindle is then worthless, unless they let you back in. That is a problem to me. If you purchased a book, you should always have access to it. Which brings up another point: you buy a real book, you always have, and own, that book. What happens, if for some odd reason, Amazon or Barnes & Noble, goes bankrupt, or gets bought out by another company who decides your purchases are no longer valid, or worse yet, your account is lost forever, and the company won't back you up even if you have proof of your purchases?
Looking at a broader picture, if all books become e-reader books, and no longer physically printed, then a disaster happens which makes access to those e-reader books impossible, what happens to the knowledge contained in those e-reader books? An e-reader is only as good as the ability to access what is saved on a micro-chip, or saved "in the cloud" thru the internet. In a major long-term disaster, (war, severe depression, etc.,) necessary information won't be available thru an e-reader. That's just something to think about.
There is a project going on, since e-readers were brought out, that someone is trying to collect all printed material, to save and protect it against the eventuality that printed material may no longer exist. That will be one gargantuan task, but an important one.
I haven't bought an e-reader, yet, but the idea sure is tempting.
