Since 5 year I use to this series Dell Inspiron 3420 was osom in that price. I have it of i3 processor was too good in windows 7 as well now using windows 10 running too good than other brand of same price. Its speaker was full of sound with cool base.no need of extra usb speakers like in other brand laptops. And battery was too portable with nice backup. But its cd RoM was not so good. Processor was soo good smooth running multiple tasks at same time. Keypad was soo smooth because typing was too easy to use. Specially its black colour was amezing. So I prefer to useee .???
