I have given up with the weird keyboard, 2 weeks of constant use in and I still cannot even get to 5% of my typing speed, and it's so much worse than that trying to do any programming. I think the proportions of my hands means my fingers can't reach the needed keys, and my thumbs can't reach half the meta keys in the thumb clusters. I shall sell it on via ebay and hopefully recoup some of the cost, and I've already ordered something closer to "normal" but still ergo and mechanical.
