Still waiting for Apple to develop an iPad-inspired keyboard, i.e. no physical keys anymore. Instead a slab of glass with a display benath (ideally ePaper to save on energy consumption), combined with Apple's trackpad-like force touch to simulate tactile feedback on keypress.
No problems with dirt in the key mechanic, no key marks on screen when MacBook is in the backpack and perhaps even less weight. And cost savings, as Apple does not have to produce dozens of varying language-specific keyboards. Should be a feast for a bean-counter.
I know that quite some people are skeptical about that, but then there are quite some people being skeptical about scissor-type keyboards, as they see micro-switch technology as the only way to build a keyboard.
Hopefully Ive's stepdown does not mean that thinness and miniaturization is of no value at all anymore at the "new Apple".
There were Apple patents posted with such keyboard, so they considering it.
