Same here. I got one from my wife for my birthday. I don't know if it's due to the shorter pages (reformatting layout), clear easy text, a battery that goes on forever, or just the excitement of a new gadget - regardless, I've already read 2 books. The eInk is amazing and worth every penny.
I'll third that. I was dubious for a while, decided to get one for my birthday. Definitely the right move, fantastic device.
Fourthed!
That is what I would like for Christmas. I am thinking about buying one for my kids too.
