This is yet another worst operating system by lenovo which consist of lots of malfunctions. This system is reviewed by many as not user friendly ccompared to other platforms. This laptop is very slim and easy to slip out of our hands and charging ability is very poor. It is waste of money in thousands for a laptop because of many consistent maintenance errors which are reported more times. This laptop when given to service centers for repairing it probably would take more than month showing poor customer support. If you want a laptop to work with in a daily basis, I would recommend you to buy another one.
