I've recently decided to buy an e-reader and have been researching different ones, but all of the choices are making it hard to decide. So I'm asking you kind folks for help.

What I want:
1. E-Ink screen that minimizes eyestrain. (I have bad eyesight and thus place reading materials within a few inches of my face, which causes eyestrain quickly.)
2. Inexpensive- under $150
3. Memory expansion- I plan on having as many books as possible, ie in the thousands.
4. Good collection management- I'd like to be able to categorize stories by author/genre/etc in easy to access folders. I don't want to have to scroll through all my books just to find the one I need.
5. Small form factor- Can be held in one hand and carried around; will fit in a large purse. I'm not really a fan of the larger physical keyboards because it seems like they add unnecessary bulk. If it's a well-designed keyboard I'll try it, but the Kindle keyboard and others like it just look ridiculously annoying.
6. Supports multiple formats/or will read books from various sources. I'm still sort of hazy on all the ins and outs of ebook formats, conversion, and so forth, but I know I'd like to be able to put fanfic from online on the e-reader.
7. Durable and/or available accessories to protect it from getting broken 8 seconds after purchase.

What I could care less about:
1. Wifi/3G
2. Music playback
3. Fancy branding
4. Apps/web browser/rooting capabilities
5. Pictures- I don't care if I can't see book covers. I just want to read text.

Thanks for the help.
