Not a universal view
Some users, me included, don't have many peripherals in my daily life that need a USB slot, data cable, no do use the SD slot, USB cables or external monitors. My iPad Air and Keyboard is almost good enough for me not to need a laptop but the lack of some software and the touch screen get in the way a proper user experience. So I end up having three things with me when with the new MacBook one will do. A lighter MacBook that just needs charging once a day would be perfect for my daily away from my desk use so don't assume that your usage pattern is the only one that Apple are addressing.
