I am assisting my father in selecting a new Apple laptop and it is between the 15 Inch classic Macbook Pro and the Retina Macbook Pro. He likes the resolution of the 15" classic macbook pro (1440x900). I am wondering how the icon sizes and/or size of the text displayed on the retina screen compares to the classic macbook screen? Will everything appear smaller on the retina display? Or is everything scaled for the retina display. Thanks.
