I've had over a dozen split or mechanical keyboards over the years. By far the most comfortable for everyday usage (software development) was the Matias Ergo Pro. The keys are outstanding. The layout is terrific. The keyboard is completely adjustable so the R in RSI is vastly reduced, I would move mine around constantly. But the quality is atrocious. After less than a year mine was repeating some keys and not registering others. The company rep told me this was normal but sent to me a replacement anyway - and that one had the same issues a year later.

That said, if money were no object I would just get a new one every year. That's how much I loved that keyboard while it was working.
