My suspicion is that the touch screen will evaporate on Nook 2.
Think about it. The cost of manufacture has become the first concern. The Kindle has a keyboard, which must cost much less.
B&N has to face facts: the touch screen adds nothing to the reading part of the experience and actually is confusing to a lot of readers.
It also adds a large drain on the battery.
Finally it is bright and shiny and glares in a dim room, which always annoyed me.
I know that there will be partisans who absolutely *love* the touch screen.
They should start the mourning process now.
