My comment obviously implied adding the sensors to make it work, Surface Laptops use IR as well as far as I know...

My point is more that why make a big deal about shipping dead tech to the laptop if this truly is what they consider the future and a better system.

My guess is Apple isn't worried about being consistent. They will provide the best solution according to the tech available at the time and the other constraints of the product.
