All the best Romain. It's been great adventure for you I believe and we were always amazed by both - what you delivered and how you talked about it. I had the privilege of working with Android team (in Google Krakow) before the G1 was released and this was quite a ride indeed.
Maybe that's a good time to speak about your "past" now at our mobile dev conference in Warsaw? We have few days left to close the speaker's list: http://mobilecentraleurope.com
and we would really, really love to have you here. Our official partners: Google Developer Group Poland can help with all arrangement if you would like to come.
