Alienware 13 Review
 

If you want a reasonably small and portable gaming laptop, the Alienware 13 is one of the leading options on the market. With its 13.3-inch display, the footprint of this laptop is smaller than a typical 15-inch laptop, and if you're willing to put up with extra thickness and weight, it's possible to use it as a portable workstation instead of an ultraportable.
