I am VERY happy with mine, but it may not be my last, since I have more than one computer. I type a great deal for work, often 10 - 12 hours in a day, and I own every keyboard known to man, including ergonomic boards. The Deck is absolutely the best one I have used.
So much of keyboard use is subjective that I was a bit uncertain of buying one sight unseen, but the 30 day guarantee made me feel better, and the keyboard itself has much more than earned the guarantee.
Shame about the keycaps being discontinued, tho, but I got a couple sets from the distributor, so I'm good.
Also, the response to emails with questions was very fast and thorough. Thanks, Adam!
