Acer Aspire is good for battery backup and not that much weight for carry easy to carry and function of this laptop is good and long lasting of part but the window vista is so slow window which I got at the time of purchase looks also good and very strong easily not destroy so that I found it good laptop value of money is quit high and service is not good in our area I want to change my cabinet and screen support but not availability and some parts are also so costly and for support things is o level there is no support but laptop run smoothly and for function level it is very nice
