Pure power wise, its exactly matches Surface Pro.

Additionally the benefit of having a better keyboard is a big factor in Laptop's favor.

hey abhay i noticed that comparison too, but its not only similar in specs but price too. both the surface pro and surface laptop at these configurations are the same price, but the surface laptop has a built-in keyboard whereas the surface pro doesnt have an included type cover.
it doesn't have the pen in the box either. so if you want the keyboard and the pen you are gonna spend another $250
