Heavy lifting is done on the cloud. I develop web and ML stuff on a tMBP. Prototyping is done offline and the large-scale training of models is done on the cloud. My laptop is lightweight enough to put in my backpack and still leave space for groceries bought on the way home. Have a 4K display and Windows US desktop keyboard (as UK Mac keyboards are close enough to a US keyboard) and mouse. I never use split-screen as I am used to window-switching on a 13" screen.
