Query: Too much money, too little marketing sense

Way too expensive for the market it has targeted itself towards. My old iPod will do everything that this does and the books are free!! If Amazon is serious about this format, they need to practically give these things away. Under $100 would be a perfect entry level price for the masses. Charge what you want for the accessories, you need to get these into the consumers hands in a big way. Now onto the books. That is where the real money is to be made. The more users you have, the greater the profit from the book sales. Get your head into the new age, it is the content that makes the profit, not the hardware.
