I mean I keep looking around and I don't see what's so innovative. The Razer Stealth is in the 13" rMBP's weight class, but gets a third less battery life. Alienware makes big heavy gaming laptops. Surface is a good design that was poorly executed: http://www.laptopmag.com/reviews/laptops/macbook-pro-13-inch.... Somehow, the Surface Book with Performance Base gets less battery life than the 13" rMBP, despite having a battery that's 60% bigger!

You have to nail the fundamentals before you start thinking outside the box. Surface Book, for example, had an innovative form factor, but it shipped with major bugs (heating up during sleep, screen refusing to detach from the base, etc.) Shipping a neat-o feature before it's ready for prime time is pointless. E.g. OLED is a disaster for battery life right now on typical white-screen desktop workloads.
