IdeaPad S400 comes with good configuration like RAM, Touch Screen, Processor. This S400 is slim and light weight with internal Intel Hd Graphics 4000 which is best for normal graphics. The negative point is not for games because this graphics is lacking some error. And there is no DVD drive. But overall the S400 gives best result in normal browsing and Photoshop work. It comes with Core I3 3217U / 1.8 Ghz with Windows 8 Pro 64-Bit and 4GB RAM. For this configuration, I suggest it’s best for professional like Photoshop not for gamer.
