I have a new Gen3 (lets call it Gen3.512).
My old screen suddenly died (while in the case...). Conclusion 1: e-ink screens are excessively frail.
While amazon is replacing kindles under the same circumstances, bookenn won't.
Long story short, I got a new Gen3 with FW708. And I can assure you battery life is nowhere near what it was before.
After just one afternoon reading, it's down to 90%.
Since I can't go back to 538 I just hope Bookeen will solve this ASAP once and for all.
@Tom: any news from bookeen since your last mail?
