I used the Dell laptop of inspiron series.
Dell is very trustable company in the field of laptops and computers.
The main advantage of purchasing a Dell laptop is their service. Their service is good. If you discuss about purchasing a laptop with anyone, I am sure a good suggestor will tell you about its service. I used this laptop of Dell for around 3~ 4 years. In short, Dell is trustable company for laptops and computers.
