The smallest system can be outfitted with 4GB to 16GB of DDR3 1333MHz RAM, up to 750GB of mechanical or 256GB of flash storage, a Creative SoundBlaster X-Fi audio chip, and your choice of Windows 7 Home, Professional or Ultimate. Other specs include a 2MP webcam, various WLAN and WWAN options, Bluetooth 3.0, WiDi, USB 3.0 ports, HDMI 1.4 output, a 3-in-1 card reader, and an eight-cell battery with an eight-hour autonomy.
Dell sticks with that general framework through the other two systems, barring form factor-related changes. For instance, the 14-inch can be purchased with a quad-core 2.4GHz Core i7-2820QM, 1600x900 display if preferred over the 1366x768 panel, it gains a VGA connector, and it gets six hours of life per charge with the same battery. Naturally, it's also a bit heavier with a starting weight of 6.45lbs, while the base price jumps up to $1,199.
Meanwhile, Dell says its flagship M18x is the most powerful gaming notebook available -- and at 16lbs, it's probably the heaviest too. The 18.4-incher will be offered with a factory-overclocked 4GHz Core i7 Extreme, dual-graphics chips from both Nvidia and ATI, support for up to 32GB of RAM, a 1080p display, HDMI input, and five programmable keyboard keys. Pricing starts at $999, but you can expect to pay far more for a fully loaded model.
