Acer Aspire is a best series of Acer family, which have all the features of Windows 7 Premium 64-bit.It is really useful with all respect as it is light in weight, fast action, can play high defination games easily.It also have 3GB Ram size, 500GB HD, Processor speed 1900MHz.If you take opposite side it has one minus point that is it’s battery backup is very low or about 3hrs. So overall it is a best option available in acer series.
