The prototype backers have started receiving their boards, the software has been ported over to Linux and Mac OS X and the shipping date has been delayed. OK, so maybe that last one is not ideal, but it was necessary in order to ensure that everyone receives a working product free of major errors. The new expected ship date is Jan 1st. Hopefully there are no more issues going forward.
In the meantime, feel free to look at some screenshots of the interface:
