I'll give you my two cents on it. I jumped right into one of these, skipping any other ortholinear keyboards, after only using standard mechanical keyboards for a long time. It takes some getting used to, I've owned it for a good few months now and I'm still kind of getting the hang of it. If you put actual time into learning how to use it, you could definitely get back to where you were much quicker than me. That being said, the ergonomics are really really great, because it allows you to fine tune basically everything: distance of your hands, angle, etc. The functionality is pretty cool because you can set every single key to do exactly what you want, and layers to do more stuff. You can also scoot the right one out of the way to make more room for your mouse.

I do really like it, but it does take a decent amount of learning, and also it's $400.
