Well my girlfriend got the dell, it has the slip drive, move your fingers on the pad like the iphone to zoom the screen in and out. Its pretty neat i do like those features.
Ive seen a few windows 7 with the slip drives. I absolutely hate mac tho.
Im not much in to gaming on laptops. I just use my 360. This laptop will be mostly graphic design (photoshop, cinema 3d etc), music editing, studio use and more. I want to be able to actually run my big graphic programs while listenin to music without it slowin down at all. Im a big multitasker and speed and rendering is the key
