I have met Laura Forlano at UbiComp2004, and again at the SASE2005 conference! She has done fieldwork in Tokyo, and researches the socio-economics of wireless spaces! When we met for the second time, she showed me this incredibly cool Szoda, free Wi-Fi café in Budapest, a node in a network of communities… I couldn’t help, designer and architect that I am, ask… If I want to travel light, do I bring my laptop or my USB key?
