L.P.
I have the b&w Nook and love it, however, I often think how much I would love the top screen to be color when shopping for new books. I could be wrong, but I think I read that the Nook color has touchscreen on the top part, too. That would be great! It took me a couple of weeks to stop touching the top screen (I'm a blackberry user and I'm used to the top screen being touch). Once I stopped jabbing my finger at the reading surface on the nook and started using the lower part...all was fine :) Can you go to a local B&N store and play with both of them? You might get a better feel if you actually get your hands on one.
Enjoy reading!
