Now I have purchased this laptop before 2 years there are many negative traits than positive one let me begin to you with the negative one
1) its weight
The laptop is too heavy and will cost you shoulder pain when you carry it you cannot easily take it anywhere . If you are the one who travels a lot then this laptop is not preferred for you.
2) heating
Yes this laptop has outlet for removal of heat on its left but the laptop becomes more heat and I transfers it to your Laps which will cause you discomfort and prohibits your usage for long time
3) cost
The cost of Dell laptops is usually higher compared to its competitors although they provide the same specification the Dell laptops are preferred only because of the service they provide and not because of specification.
4) variants
There are lot of variants but only few variants are good and usable for a long time you have to check in the configuration and buy the most
Suitable one for you.
