The latest release from Dell-owned Alienware, the M18X, is a behemoth with enough power to run any game under the sun without so much as a flicker. But you'll have to have deep pockets to get your hands on one.
Even getting the M18X out of the box is a challenge, thanks to its 438 x 311 x 52mm dimensions and a back-breaking weight of 5.7kg. This machine was designed to dominate your desk. As expected, it sticks to the Alienware design, which we love, but probably won't be to everyone's taste.
The entire machine is a slab of moulded rubber and brushed metal, and that ever-present Tron-style neon backlight.
Unsurprisingly, the focus of the Alienware is gaming. Our review sample came with an AMD Radeon HD 6900M and scored a mind-blowing 19,056 during our intensive gaming benchmark test.
While the sheer power of the machine keeps games running perfectly, it is the 18.4-inch screen that made playing on the M18X a truly immersive experience. The Super-TFT screen is like a window into your games. It's extremely bright and the 1920 x 1080-pixel resolution keeps the most complex graphics razor sharp.
But it's the sheer size that is the winner here and you really notice the difference between this and a standard 15.6-inch machine.
Although we like the keyboard on the M18x, there is a degree of flexing towards the centre and some might not appreciate the tightly packed keys, but the customisable backlight looks great.
As any gamer knows, you're going to want a mouse, game controller, joystick, or any number of other peripherals to get the best from your laptop. So Alienware has gone big on connectivity. There are five USB ports, upgradable to USB 3.0 if you want, along with an Ethernet port, eSata port, VGA Out and audio jacks for your headset and microphone. On top of that, you get two HDMI ports for connecting extra monitors or an HDTV.
Despite our praise, the M18x is not without its faults. At 87 minutes, the battery life is woeful. The charger, like the laptop itself, is huge, and you certainly won't be leaving the house without it.
The other problem with the M18x is that to play big, you have to spend big and, being custom-built, it costs a small fortune to get the best spec. Every model runs on a Sandy Bridge Core i7 processor, but there are different variants available.
Our review sample was powerful, but other laptop components such as RAM and storage space were poor. This was disappointing and, although you can customise the amount of storage, we would expect more than 250GB and 4GB of RAM for £1699.

Essentially, if you're not a hardcore gamer, there is no reason to spend this kind of money. But if you want the best mobile gaming experience around, this is what you should be looking at.
