Blank keyboard user here (custom ones from WASD Keyboards). I felt no difference between this and a regular keyboard, mostly because I was touch typing anyway.

Programming is surely more thinking than typing, but once you're in the flow, it helps to just write away and the keys simply vanish. Unfortunately the new Macs have really borked the typing experience, which was the main reason why I purchased the blank keyboard. There's something about reducing the friction between your mind and the problem that I find fascinating, even though the bandwith of the "fingers on keys" channel is still rather low (unless you go all out bionic fingers like that schene in Ghost in the Shell). Another, maybe fictional, reasoning to get a blank keyboard was to be able to type properly even with a VR headset on. There's only one major drawback in my experience: position in front of keyboard. Sitting on the sides or typing side-ways (like in some pair-programming situations) becomes difficult, even if you follow the home keys.
