Does alienware notebooks like area 51 extreme come with the alien ice cooling system because in the clip of the "alienware difference" it says there is an alien ice cooling system. Is alien ice better than any other cooling system?

Maybe try asking alienware :). Give 'em a call.

i would think its a marketing gimmick, but you'll never know. like xtr-x said, give 'em a call

Alienware are so far the only company that offers notbooks with upgradable graphics chips. That's a pretty good selling point, and one that other manufacturers will soon offer. I wouldn't worry about marketing gimmicks, as alienware would not offer a notebook if it didn't meet their high standards. Alien-Ice, as far as I can see, is simply the provision of an additional air duct to supply cool air to the video card. It doesn't feature in their mobiles as far as I can tell.
