Summary: Received my laptop in just four days, so, full marks to flip kart for home delivery. Dell Vostro 2520 comes with ubuntu so if are not familiar with it you are going to suffer a lot.you have to get windows installed yourself along with all drivers; so, here It really hurts. Product body and overall look of the laptop is good. Bluetooth speed is good. Battery lasts for max 3 hours its okay.
