why alienwareI wanted something with a good video card and a 15-15.4" screen. The Area-51 m5500 is 6lbs, 1.4" thick, and has a 256mb GeForce Go 6600. Dell's notebooks seemed very polar (either tiny or huge, cheap or expensive, supermobile or desktop replacement), while this one seemed very balanced. Alienware has great customer support (they are extremely knowlegeable and courteous), and the system just looks sweet. Mine only set me back $1600 shipped, which means they're a good value too. Check out some reviews and you'll know why to go with Alienware.
