I got a das keyboard at home and at work. Its awesome, and I'd recommend a mechanical to anyone who works on a keyboard for a living. I would never buy anything like this from Atwood, though. His 'expertise' in software, personal attacks on other developers and tedious self-promotion don't really convince me that he's got the know-how to get into hardware production, but rather that he's found a way to make money off his sycophantic fan-base of mediocre programmers who take his word as gospel.
(remember Arringtons tablet, anyone?)
