The 700 was priced too high in my opinion , because if it's between the kindle 2 and the sony 700 , same price, ... kindle 2 will WIN, because of whispernet and clearer screen, and all the other goodies. The prs-505 is selling because the price has dropped and it's 100 dollars less then kindle 2 and has same clear screen.
It would be nice if sony did have bigger model that could even be bigger then Kindle DX that displays pdf's the way they should LOOK! And 100 dollars cheaper then DX!
