thank you for the reply - I notice you updated your message as well
I'm interested in why you prefer the Kobo over the Nook. I don't really want a backlit tablet, since the whole eInk and battery life are what I'm after. Now assuming you didn't already have an Android tablet, would a rooted Nook be an obvious choice over the Kobo?
What is it about the Kobo you like so much more?
In my opinion, I'm not really comparing Nook vs Kobo, i'm comparing Android with eInk vs Kobo (the fact it's running on a Nook is somewhat inconsequential, other than the ergonomics and form-factor).
