The downright winner in any Lenovo contest would be the IdeaPad 720S. This laptop defies the adage of "you get what you pay for". Its way better value for money than some £1000+ portable laptops with its independent graphics card which means it can even be used for gaming.
It can do this without killing your battery life! So no need to constantly worry about your laptop charger.
The one downside is that the laptop doesn't have the Nvidia's latest GeForce MX150 graphics card. It instead opts for the slightly dated 940X instead. Although, this doesn't make too much difference in performance, but for sure, it would have added significantly to the price.
