Its casing is metal. This is somewhat rare in laptops but really adds to the premium feel of it as well as making it quite durable.
It is super fast. This laptop can be configured with dual ssd hard drives in raid 0. Thats mindblowingly fast (and expensive). It comes with some nice high end graphics which allow it to play the vast majority of games and max settings and also supports 3d vision (more on that later) it supports intels latest mobile i7 processors and can be configured with 16 gigs of ram.
It looks absolutely awesome!!!
It has fully customizable lighting that you can change it to any color you choose.
It supports an awesome technology called 3d vision. A 3d gaming technology that does not require a proprietary display. All
