i've had the dell xps m1330 laptop for a total of 3 days. so far, so good and i didn't even get top of the line. much faster than my last computer and i'm actually able to run several programs without delays at the same time. 6 cell battery lasts about 2 hours. i'm still getting used to microsoft's vista but haven't encountered any problems yet, however i have not tried out all the functions on vista. computer is light and very portable but not as light as i thought it would be - i think mine is 5 pounds - my last laptop was double the weight.
