Own the AO750 ,somehow bought at walmart as they were being pulled off the shelves on release day; my first laptop. Simply geat so far...but as always looking for "more power". If anyone out there spends a lot of time at Dr.s, or in the hospital?- these are priceless. And will Never fall behind paying my bills again while 'Inside" -- the hospital-ever again. Thanks for the Newbie section and advice, all!
