Power hungry intel chips and graphics cards are inconvenient in laptops when it comes to battery life and cooling. It is especially noticeable if you spend any time using an M-series macbook pro, where performance is the same or better, but you get 16 hours of battery life. I prefer to use thinkpads, but apple just has a big technological advantage here that stands out in the UX department. I really hope advances are made quickly by competitors to get similar UX in a more affordable package.
