Not a terribly important question in the grand scheme of things, but what's the rationale behind making the \ key and the Enter key touch each other? I've seen it on other keyboards as well and cannot imagine what's gained by doing it.
The purpose of this feature is to ward off those of us with design OCD. We are the most annoying users to support
Perhaps it's to make things (slightly) easier for people used to ISO layout keyboards? You could set both touching keys to be enter, and not have to relearn muscle memory - kind of, because you'd still have a weirdly long lower-enter compared to what you were used to.
