Only the external standard layout will really do for look-free pressing of all the useful keys.
So I stopped expecting anything beyond a couple minutes out of laptop keyboards and always carry a standard-enough 104-key.
I first began this practice when I had a laptop with a few missing keys, but soon I realized how much better an external keyboard is, and how little extra weight it adds to my bag.
