I'm looking for an e-reader that has to read any PDF, text files & possibly a word processor. Being restricted to use the manufacturer or original seller content is a deal breaker. The charge should significantly longer than a laptop, 8+ hrs seem a good beginning and 12 hrs would be nice. I'm considering purchasing a used model as I'm looking for something quite affordable (new is also an option (if the price is right)), but the maximum charge could not have diminished so much as to not meet the previous criteria. It would need to be large enough to see the normal content of a Letter (8.5x11") page to be shown (OpenOffice Writer default Letter page has for margins 2 cm (0.7874")). Neither color nor back-lighting need to be supported, although it has to be better than monochrome, 8+ colors grey-scale comes to mind unless... the monochrome is at a quite high DPI using patterns which would end up looking like a grey-scale (think of early 80s monochrome graphics), and the device would have to handle the transition to monochrome.

In counterpart of the long charge I know I could not expect a quick change of page, I'm hoping ~5 secs and really hoping <= 10 secs. One thing that the device cannot take > 1 min to skip multiple pages, ie: going from the TOC to the index, in essence skipping the whole book content. I understand the CPU would be taking a hit and skipping pages would possibly take longer than displaying the next page, but it has to be within reason. I'm also not requiring features such as PDF bookmarks to be implemented without becoming significantly slower, I'm happy to enter page numbers.

I'd love if search would be supported, even if it took a good amount of time (still about: processing capabilities VS long charge). Hopefully it would also read multiple word processors (files), web pages without images, desktop publishing (ie: Scribus). I don't foresee the necessity to consult a web page a with image as a document export, I wouldn't say no to it but it's far down my list of priorities (PDFs & text files being at the forefront).

The essential peripheral, recharge & connectivity, would need to be included in the price (the don't need to be in the same purchase but their total, S&H included, should be low).

Thank you kindly for your help

Update 1: I must have been pretty tired writing this. PDF locking has to do with editing, not reading.
 
What you're looking for, in essence, is an (Android) tablet with eInk screen. There were similar two-screen devices in the past, but they quickly went into oblivion.

I am not sure your long list of requirements for "universal" document support can be met by any current device. Using off-the-shelf readier (Kindle, Nook) with Calibre would give you most of what you want.

Couple of years ago I got Kindle DX, and still use it.

I have not looked at your suggestions (I read them but not made a search for) yet but I will, so I might get back to you about that post later. For now I'd like to address

everything in the OP 3rd paragraph is optional; the documents for the 1st (paragraph) mention "has" and the 3rd "love".
