Well, to be honest and all: I hate Dell computers. why? because I dont like the design.
And no, I am not an apple-fanboy since all they like is the looks of an computer, I have made my own gaming rig inspired by the Alienware.
So yeah; my idea:
Change out the ugly backplate for the screen and make it more likeable, you've hade the normal Dell logo with the circle around it for ages!
The "Dell" and the line will be lit up with a backlight or some sort (just like the mac, but "you dont say?" The thing that makes the mac sell so much is just the pretty design) so yeah, just an idea
