"If nobody says what he or she thinks is wrong about a device, how will the manufacturer be able to remove flaws? Or, worse, even know what the public wants?"
People speak with their money. If Apple does not sell many iPads, they will add/take away features. Apple does not go to Mobileread forums every day to see if the few dozen posters like their as yet un-released product.
That being said, I was trying to be helpful and offer what looks to me a good alternative for those that want a full OS pad. By all means, keep whining about the iPad!
