Greetings,

I'm looking for an e-Ink reader that I can use at work.

This means several key features:
1. Needs to open .doc (.docx a plus)
2. Needs to open .pdf
3. Needs 9+ hours of battery life
4. Needs wifi access (if no wifi then needs to be linux compatible for any
copying of data)

Reading of other files types a plus, but not needed

I welcome any suggestions on what I should buy.

Thank you,
Cocytus
