Front Facing Camera and Rear Facing Camera

Camera :  Front Facing Camera 5 megapixels minimum
                        Rear Facing Camera 8 megapixels minimum with
                        autofocus (SONY-made) just like in an Android
                        Smartphone or Windows Smartphone .

I STILL THINK A GOOD QUALITY FRONT FACING CAMERA AND A GOOD QUALITY REAR FACING CAMERA IS A NECESSITY FOR TAKING DECENT QUALITY PHOTOS AND DECENT QUALITY VIDEOS IN THIS  17 INCHES  DELL  MACHINE
