so, after all is said and done, once the color nook has been rooted, which is better, the rooted color nook or the xoom? basically my wife is trying to decide between the two, she is in realestate, she really won't be using it for movies or games, she is a very casual gamer, like Angry Birds, and that's about it, but mainly she will use it for business. so, which should she go with? which, has a better processor, speed, connectivity, etc. , etc.?
