Hi. I'm an avid reader and I own a nook (2nd generation). I'm interested in getting an e-ink reader such as a first generation nook or a kindle but I want to buy a used one.

What I'm looking for is an e-reader that will allow me to add and read new content without needing to create or sign-in to an account (B&N, Amazon, etc) and that will continue to function for the foreseeable future regardless of whether or not the company that produced it supports it or even continues to exist.

From what I've been reading the 1st gen nooks are out and I think the same is true of older kindles so I'm assuming if I picked up a kindle today eventually it would go obsolete as well. Of course if there are any hacks (suck as unlocking) which would enable me to add new content to these devices that would be an option.

I know battery life will eventually become a problem and there isn't much I can do about that unless there's an e-ink reader out there which uses easily obtained off-the-shelf battery types but I doubt it. But I would consider this problem unplanned obsolescence what I'm trying to find right now is an e-ink e-reader which isn't planned to become obsolete or which would most likely become obsolete if and when the company behind it decides to stop supporting it.

Any ideas?

P.S. I'm not concerned with the ability to obtain content from the B&N store or Amazon store or any other specific "store" but rather epubs and other standard DRM-free content.
