(That said, I have to agree with one of the other child commenters here-- the current Magic Keyboard is actually my favorite of Apple's recent keyboards. Similar feel to the tbMBP keyboards (more crisp and clicky than the older keyboards from the pre-touchbar rMBPs), with a bit more travel and a more robust mechanism, and the numpad version has a nice, big T-layout for the arrow keys rather than whatever the heck is going on with the arrow keys on the tbMBP.)
My favorite keyboard ever, though, is the current 'Magic Keyboard'. It's like the perfect medium between the old chicklet-style that felt rather mushy to me and the new butterfly mechanism that's almost too rigid.
Sadly, it seems Apple does not want to go back to that feel in their mobile line :(
The grip I have with the newer Pros is the *@($ Touch Bar. It's sad that the new Air has exactly what I wanted—addition of Touch ID but no Touch Bar—but the so-called Pros still have the Touch Bar. I have yet to find a touch typist who believes the Touch Bar to be a good reason to pay a few hundred extra for it.
My favorite keyboard, beam-spring being a thing of the past, is the Model M (Unicomp still builds them). I love it, even if my family would rather have me not typing after 10 PM.
Someone else said it, the new Apple wireless keyboards are great. I have one at work and at home.
