I am using Dell Inspiron15 - 3000 series for the last 2 years.It has a fantastic look like outside colour Royal blue.It operates very fast as it is powered by a 1.8-GHz AMD A6-6310 processor; 4GB of RAM; and a 500GB, 5, 400-rpm hard drive.As a workshop trainer I need to operate it almost daily 6 hours but it doesn’t get hanged tough I use external fan to make it cool.Above all as far as my concern it is also cost effective as it has versatile 38.1cm screen with a spacious HD display, efficient performance and essential features for an optimal multimedia experience.
