In an alternate reality, Apple listens to creative pros and introduces a 17in MacBook Pro. What would the machine (realistically) be? My wishlist. Five hour battery is fine. Power cord is normal. Real, killer PRO GPU. User memory slots to 64GB. Return of ports (for now). Real, PowerBook era keyboard. Retina ISP Matte screen option. Desktop class CPU. I still need Ethernet, USB A, and a digital audio. But, I know port needs change. MagSafe was a lifesaver more than once. Would such a gesture matter? Too late?
