Apple could be waiting on their engineering department to create a thinner scissor mechanism keyboard. One the big advantages that Apple was pushing for the butterfly keyboard was the ability to have a thinner keyboard and therefore a thinner laptop.
What if Apple is nearing the edge of what is possible with current materials and manufacturing for the thinnest Mac notebooks? Apple may not be able to push forward and make thinner laptops due to heat from the CPU and GPU and the materials used to inclose the hardware. Apple’s design is already amazingly thin, why does it need to get any thinner? Let us know your thoughts in the comments below.
