I have not. The design and size put me off. Plus I really want to avoid a different key layout, as it raises my error rate (and hand stress). This is important because I move about and sometimes use a laptop keyboard.

But maybe I'll have to give it a shot. I just don't see what's so hard about taking a normal ergo keyboard and making it with proper switches.

If you need to be mobile then it may not be a great choice; it's pretty cumbersome. I've been looking at the Matias Ergo Pro which looks like a better choice for someone on the go. However, I think the layout is just something that requires a bit of getting used to; after about a month I got really used to it and switching back and forth has gotten easier with use of both it and a standard keyboard.

Additionally, not sure if it matters to you, but it is terrible for gaming.

I'm curious if this is simply some silly patent issue where people would make it but MS or Logitech owns a patent that is preventing it without significant modification...
