Note that with a keystroke (and subsequent reboot), one can switch to the Intel integrated GPU while on battery, which boosts the life on battery up to 5 hours. Note that this would be "normal" (non-gaming) use, but gives you much more time between outlets.
I was at first hesitant to purchas an Alienware due to the cost, but after having had my M18X for a little over a week now I am EXTREMELY happy that I paid the extra money and invested in the M18x. The system runs flawless, and can handle ANY game for extended periods of time with no problem whatsoever. I purchased a 3 fan cooling system to provide additional cooling for the system and it has worked like a charm. While the author seems to think that the glare from the screen is bad, but I have used this system in both outside and inside environments and noticed little to no glare. There is a company out there called Nu Image that makes a screen protector that does a GREAT job at eliminating screen glare. If any of you are experiencing ANY glare issues I highly recommend purchasing this screen protector. Overall I would say I am EXTREMELY satisfied with my purchase and would recommend the system to anyone looking for a top of the line, customer oriented gaming system!
CrossFire deluxe. Hardcore gamers who don't care to make friends with a desktop PC have come to the right address with Alienware. The massive M18x is looking for customers in its second revision now with dual GPU solutions. Does a double Radeon HD 7970M mean double the fun?
