hopefully the new firmware won't affect battery life. i'm pleased with my battery life and not so much pleased with the news i hear of the cybook's (especially the problems after new firmware came out).
oh, and sony, if you're listening.. you just made the sony reader my perfect reader (well, barring a better slightly bigger screen) except for one feature. Ability to add your own fonts (and thereby add multi language support). Other than this one thing, the 505 right now is perfect for me. please consider!
