That's interesting feedback. Thank you.
I have this in my 11.1 inch Asus x200ma. Compaired to other "netbooks" I have had (at 11.1 inch the x200ma is not really considered a netbook, but it is) this is hands down the best one I have had. Previous: Lenovo s10 with atom n270, horrible. And a couple of gateways I cant remember the models of, all had Atoms, all were forced to have 2gb ram or less, could barely run windows.
