I got the email about this today - I've been on the waiting list for about two years.
I find the company's approach to all this a tad pretentious - it's a keyboard for goodness sake. Admittedly it will probably be a nice one, but it isn't going to halt the planet in its orbit.
I doubt that I'll be ordering one next week, and then waiting until December to get it - life's far too short for such complexities. Anyway, I'm already using the best keyboard since time began.
