Hi all today I am sharing my personal experience on Acer One S 1003 notebook my brother has purchased this laptop 4 months ago and this laptop is not good because it will be hanging always when we are doing some work or playing games and it has 4GB RAM compared to other laptops it is very slow working and music quality of this laptop is very worst and the camera of this laptop is not clear and the main part of any electronic device is the battery and this battery pickup is not so good it will come only for 2 to 3 hours and it has Quad Core processor compare to other laptop it will work very slow I am really very UN satisfied with this laptop
