The Lenovo netbook family has a new sibling: the IdeaPad S9. It was announced as far as August and is quite identical to its’ older S10 except for the screen size. I have written before that the future of ultraportable notebooks was 10″ but for those who think that a 8.9″ screen is really going to make a difference in portability and weight, the Lenovo IdeaPad S9 is for them.
