Automated Draft Beer?

Ok so I'm sitting in the Narita airport and I noticed they had both Asahi and Sopporo on draft, self-serve styles. Toronto airport (Air Canada lounge) has Keiths, Canadian, and Blue on draft that you pour yourself, so it was not entirely new to me. However this machine was different -- it was Japanese after all. There was a single button with instructions 'press once'. There is a little metal tray at the bottom where you put your glass, you press the button, and the metal tray folds forward causing your glass to tilt and then the beer pours.

I get the intention -- its meant to pour a nice beer with less head because its smart about the tilting. But I still ended up with a huge head, so it begs the question why all this technology is required when I could have poured my own draft beer better, with a mechanism that would cost half as much to manufacture :)

All that said, the beer (I prefer Asahi to Sopporo) was still fantastic.
