I am going to share my personal experience of myself with using this laptop. .
I m using lenovo G560 from last one and half year and I m really satisfied with its service. .it has Intel core i3 processor, 3 Gb RAM, built in bluetooth cum wifi and much more. I am very happy with its wifi connectivity.It gives proper signals while using in a low network .u have downloaded many applications and many games too. that doesn't make any difference or they doesn't creat any obstacle while browsing it.
I love this company of laptops.
