It is a heck of a temptation, isn't it?
I've been trolling the Dell site myself recently. Just to open the box, and there's the computer...bliss. New car smell, my rump. There's nothing in the world like the smell of a shiny new piece of electronics when you rip open that plastic bag.
I just wish I could trust them to make the right component decisions. It's damn hard to figure out what they put in there sometimes.
