I just baught dell Inspiron 5559 with configuration of i3 -6th gen/ 4 GB RAM / 1 TB HARD DISK/DVD AND WIN 10 HOME. It is an average laptop, look is not so good . Battery life around 2 hrs 30 MNS with wifi turned on which is not very good. There is no need of any antivirus because Microsoft has windows defender. The other drawback is its weight because its quit heavy. It could be a durable laptop but thelook and built quality is not upto the mark . but the service and support is good as Dell is one of the best brand in the market. but in my opinion it is not a good laptop.
