I like the feel of the new keyboards but I've heard that they're much less reliable. (keys get stuck with the smallest of debris). And since Apple's obsessed with integrating everything now, you have to replace the entire assembly for a stuck key, which costs something like $500. And that's an absolutely ridiculous tradeoff and the epitome of "form over function"

I don't have one but my wife's new laptop has the keyboard. I really hope we don't have to deal with that.
