There'll be a tax for that. Initially, probably. Think of the long game. This is something they have already done, twice. They have the experience and expertise to make this less impactful. > Even if native apps compiled and written for the Axx architecture have better energy and thermal performance, what about all the x86 apps that have to be emulated? There'll be a tax for that. Longer battery life is always preferable in portable devices, no? Alternatively, what about the reduction in the need for the materials, therefore the environmental impact, used in making batteries for laptops? Apple want to be the greenest manufacturer.
