There's an interesting difference (for me) between the recharge requirements for my phone, iPad, and Kindle. I charge my phone most nights (it'll last into the second evening pretty reliably on a charge), my iPad once a week or so, and my Kindle fairly rarely. I do quite appreciate the long battery like of the Kindle (it's an old 4th gen eInk display model, which doesn't go a whole month any more with heavy use, but even used a lot it still gets well over 2-3 weeks out of a charge). I sometimes consider investigating rooting/hacking a Kindle to make it closer to a PDA - I suspect it's got a lot more computing power than a Newton did...
