yeah online gaming (screenshot on the other thread will show some of the games installed), tho i got others that are single players and offline but they are not on the desktop as I hardly play them, depending on my mood.
I also use it to listen to music. the xps comes with JBL surround, that plus my skull candy hesh (couldnt be asked to buy Beats...), and occasional HD movies and series.
my friend recommended the alienware but specs for what i needed, xps was fine as long as i could customize. also alienware MX series the hot air comes from the bottom of the case, while the xps is a side out only and doesnt burn my legs, unlike my friend's mx17.
battery is a 9cell. disk storage aint much since i got 2 sata externals for backups and other stuff.
mind you the laptop does weigh quite a bit!
