I recently bought this computer and I am absolutely happy with the performance it has, even I bought the basic model with an Intel i3 3.30 GHz and 4 GB, all software runs smooth and fast. I love the design and the features to conver the screen into a video display system or even a tv. The speakers deliver great sound experience even when they are internal. I have read other posts and I definitely will say that I changed from an "Ford fiesta to a Rolls Royce" compared with my old Hp laptop. (It was not so old really).
I´m a regular GIS software user and it runs great, also the graphics, colors, and size of the screen is just perfect. Five stars Dell!!
