Here is my wishlist... I was wondering if any Gurus had an opinion

Basic architecture:
- Widest possible support of common and non-drm formats (txt, html, epub, pdf, fb2, doc)
- High battery life and a replaceable battery (a relatively common battery model likely to remain in production)
- I like low contrast (so no need for a Pearl display - an E-Ink display will do)
- Highly adjustable fonts, good reflowing. Good PDF handling is desirable

Navigation:
- Keys (preferably remappable) for navigation. A touch screen is of secondary importance (although induction would be convenient)

Organising information:
- Some type of directory structure for organising books.
- Search functionality and some type of exportable indexing/note-taking capability is desirable

Special features:
- A writing application would be nice (and support for a keyboard - especially a USB one)
- Text to speech is also somewhat desirable. A web browser is nice but significantly less important
- I like customisation and open architectures. Preferably support for importing unusual unicode fonts (Cree Syllabics)
- Tolerant of cold temperatures and moisture

I'm leaning towards the Pocketbooks - as they have good button mapping, customisability, very wide format support and a replaceable battery. However, they lack a writing app (or the open architecture to make one).

Are there any better options for me?
