@Sirozha: Sorry to beat you to it. I had this idea close to a decade ago and wrote an extensive note to Apple on their Contact Us page in the hopes that they might actually do something along these lines (though I suggested a built-in component incorporating a lot of what is already built into the iPod). I had always wondered if Apple ever took the idea seriously. In any case, having a smart trackpad that supplements touch input with visible feedback would be a welcomed feature in many circles (think of how it could do with painting in Photoshop, or how it could be applied in assistive technology, to name a few).

Possibly a reason for Apple to push for a Modular MacPro that supports outsized processing capabilities and configurations is that they anticipate machine learning/deep learning to play a significant role in Apple's future.
