After using it all last night I have to say I am very happy. I watched Lisa's MobileTechReview on the Kindle Touch from YouTube then I was posting here from the Fire and then I read on the Kindle app for a bit using Sepia that SCION so dislikes. After awhile the text look black to me instead of brown.
I have to use Screen Filter the whole time as it's way too bright but with that app it's manageable with lights on. Lights off I am still trying find a way to use the Kindle app it's too bright.
I ran the battery to 23% after heavy use. That's 16 hours and it was used alot yesterday in those 16 hours. If you keep WiFi off when not in use it last a long time that battery is amazing! Out performs my netbook's 9 hour battery hands down.
