Earlier on today we published a review of the M11x R3, Alienwares latest revision of their excellent ultra-portable system. That isn't the only product being launched by them today though; we also have the M14x and M18x which expand the range that already includes 15" and 17" models. The M18x as the name suggests is an 18" model and we have been putting one of the first samples through its paces over the last few days. Join us as we find out through a selection of real world tests what Alienware can do when they have an 18" chassis to play with.
