I bought this Dell Latitude System in 2013 Dec. The main reason I bough it is the brand value and reliability of the DELL products. The system came with a 2.9 GHz quad core CPU, 6 GB DDR2 Ram then.
With 1TB HDD and Windows 7 64 bit Operating System. The system If you compare now in terms of thickness and weight it might not stand a competition. But it still performs like a Range Rover of Computers.
It can easily process any task thrown at it with ease. Still a mean machine. And Have had no issues with it since all these years.
