I learned about the Nook Color over the weekend. It has the potential to be a really good Android tablet ($249, 800MHz A8, 8GB storage). Only thing is that it's restricted to running apps approved by B&N, and it's running 2.1.
They got it to boot from an sd card, which is a step in the right direction. When it gets rooted, it will be one hell of a tablet for its price. Is this a loss leader for B&N? It seems very cheap for its build quality.
