That's definitely an innovative way of filling it from the bottom, using a magnet, and the fact that you can remove it & take it home with your teams logo on it is cool, I like the customer review of it, "Finally a reason for it to cost so much".
Unfortunately it says that the home unit won't be available until 2013, so still a few years away from having it at home, although it does say that there will be a few times before then when it will be available to home users if you subscribe to there mailing list.
