Hot Heart

Battery life is totally moot. For either device it is measured in weeks / months. A few days here or there is not an issue. I'm sure Nooks are great and all. In my experience, the kindle has a perfectly good font, is inexpensive (at least by my standards), has a great library, offers regular deals (I picked up Game of Thrones for 99p) and is a beautiful piece of hardware. I've never used a Nook, they're probably comparable in all areas bar marketing.

I think they're very comparable but sadly Nooks are overlooked despite being better deals simply because they don't have the brand recognition Amazon built up back when the Kindle was the only one doing this.

Doesn't really help that they're not available over here (yet).
