The M15x is Alienware's latest gaming notebook, featuring an Intel Core i7 processor, 15.6-inch screen, and Nvidia GTX 260M graphics. Is this monster worth its asking price? Read our review to find out.
Our Alienware M15x has the following specifications:
The M15x starts at $1,499 as of writing; it is available in three colors: Cosmic Black, Nebula Red, and Lunar Shadow (silver). Our test unit's price is sky-high mainly due to the Core i7 920XM Extreme processor, which commands a $900 premium over the base Core i7 720QM processor.
Build and Design

Alienware is known for its out-of-this-world designs and the M15x is no exception. Following the flagship Alienware M17x, this is the second notebook to use their new “Stealth” look. The M15x has a one-of-a-kind look and feel.
The M15x is unusually large for a 15.6-inch notebook, measuring almost two inches thick and weighing over nine pounds! The front of the M15x is striking; it is slightly pointed outward towards the user and is flanked by two menacing speaker grilles. The front of the M15x is not vertical but angled downward as well. The lid has a unique look; it is very tall and angled at the top to match the chassis front when closed. I like how there is a dedicated area for grabbing the lid at the top.
The M15x is a very well-built notebook. It has a strong internal frame and takes significant force to flex. The lid is impressively strong; it resists twisting noticeably better than other 15.6” notebooks thanks to is one-piece wraparound backing. The lid is firmly secured to the chassis by a strong hinge. Generally speaking this notebook is extremely solid.

While the build quality of the M15s is impressive, it does not feel quite as solid as its bigger brother, the M17x. The M17x uses anodized aluminum for the chassis and lid back which is heavier than the M15x's magnesium alloy but feels more solid. The M15x has class-leading build quality, but aluminum would make it better.
One feature that deserves special mention is the AlienFX customizable lighting system. There are several different lighting zones; users can choose many different colors for various zones on the notebook, including the four parts of the keyboard, touchpad, media buttons, power button, Alienware logo below the lid, and alien head on the back. The colors can be changed from the Command Center application:
The lighting can be turned off at any time by pressing [Fn] and [F11]. AlienFX is truly unique and adds aesthetic value.
Screen and Speakers
The M15x has a 15.6” LED-backlit screen available in two resolutions: 1600x900 and 1920x1080; our test unit has the latter. This display is positively gorgeous; it is extremely vivid and has excellent contrast and brightness. Backlighting is impressively even and viewing angles are well above average; this display has near-perfect horizontal viewing and a generous vertical range. The display's surface is covered with a single piece of “edge-to-edge” glass, which means a lot of reflections but a seamless look.

The speakers are above average with ample volume. Sound quality is not especially high however is acceptable for gaming and Internet videos. The M15x has two headphone jacks; take advantage of them for a better audio experience.
Keyboard & Touchpad

The M15x has a full-size keyboard but no number pad. The keyboard is quiet and the keys have a rubberized finish for better traction. The tactile feedback and key travel are good; the keyboard has a slightly rubbery feel which is pleasant. The keyboard is communicative enough to type quickly and accurately. I like the arched spacebar.
The touchpad has an overly-textured matte surface. The heavy texture prevents full finger contact with the actual surface and makes using the touchpad unpleasant; the mouse appears to lag across the screen while tracking due to the less-than-adequate contact. The two touchpad buttons work as expected though are somewhat noisy.

Ports and Features
The M15x offers an ample port selection. Both VGA and DisplayPort are included for external video connections, however I believe HDMI would be more appropriate than DisplayPort on this notebook since it is better for connection to HDTVs. All picture descriptions are left to right.

Left Side: Kensington lock slot, power connector, VGA, Gigabit Ethernet, DisplayPort, USB, IEEE 1394 mini-Firewire, 8-in-1 media card reader

Right Side: ExpressCard/54 slot (top), slot-load optical drive (bottom), dual headphone jacks, microphone jack, eSATA/USB combo port, USB

Rear: Exhaust vents and hinges

Bottom: Vents, battery, and custom nameplate
