Screen, Interface and Form Factor

The M15x comes with a slightly larger fifteen inch screen than standard consumer laptops, measuring 15.6" diagonally. The default is a 1600x900 white LED display, but for a mere £20 extra you can upgrade to a Full HD 1920 x 1080 pixel screen. Again, I imagine that for a gamer this upgrade would be the very epitome of a no-brainer.
In terms of size, this laptop is portable, but certainly no lightweight - it tips the scales at just over 4kg, with a width of 14.88", height of 1.92" (when closed) and a depth of 12.15". In fact, this may be an ideal compromise for gamers who like to move their rig around a lot - its a bit heavier than a standard laptop, but immensely powerful, and still significantly less cumbersome than its big brother, the M17x.
The keyboard is slightly raised, and each key has a backlit border which is useful for locating keys in a darkened gaming chamber, but this backlighting also has the additional advantage of making the laptop look pretty fierce. However, this model doesn't feature a dedicated numeric keypad - you'll have to scale up to the M17x for that.
Alienware M15x Battery Life
The default configuration ships with a 6-cell 56Whr battery, but it should come as no surprise that the M15x is something of a power hog. Despite the improved efficiency of the Core i architecture, this machine will drain your battery faster than you can say "Call Of Duty". This may not actually be much of a problem, as you will probably just be bringing it from your home to a LAN party and plugging it in again, but if you want to actually use it while running on batteries, then you should upgrade to the 9-cell 85Whr option.
