I'm going to ask "why?!?!?" I actually had a MBP 15 inch retina display and returned it. What really pisses me off is where does Apple get off charging so much for what they actually put into their computers. I understand the appeal of the MBP and I even think it's damn sexy but for what I can get for the price I just cant give apple my money
I wholeheartedly agree on the 'terrible value' on the MBP, but I personally just weigh portability, battery life, screen quality and overall build quality above the actual performance of the machine.
My logic being, what good is a laptop you won't carry around?
