Yeah, I just saw this on engadget and thought FIGHT!!!
B&N Nook's and Spring Design Alex could all be under threat. The only legal cases more amusing at the moment are Apple against the world i.e. HTC and Noika
Hope it doesn't damage the ebook industry having these industry heavyweights fight it out in the law courts.
On the positive note if Amazon have this patent maybe a Kindle design is on the way with a touch screen that isn't so ugly
