Sony's AIBO robot Sold Out

An Anonymous Coward writes "Sony's AIBO entertainment robot sold out in Japan in 20 minutes. They sold 3000 units; that's more than 2 units sold per second!" Sony has been advertising this thing on Slashdot actually so I've browsed the site pretty extensively. I just wish I had the cash to fork out for one of these puppies (rimshot). They look awesome, although I think I want a version that can climb stairs...
