Honestly speaking, I can't see how you can say that Dell hardware is better than apple hardware. Its not even close.
I don't mean to be vain, but when I spend $2k+ on a laptop, I want people to go ooooo, not, blah, its a dell.
You get an apple, you get resale value. You get Dell, you get a piece of plastic.
I mean, if you really want small size + Speed, get a Sony laptop! Now those are good laptops. If its just speed you want, get an Alienware. If you want overall appeal, speed, support, and OSX, get an apple. If you want bulk government or cooperate computers, THEN I would say get a Dell. You get a Dell and you are no different then the guy on the plane next to you whose company gave him a laptop.
