I was rather taken by a post by Bill Thompson, Neo-Nomad at Large, which I read on Saturday and has stuck with me. Bill already lives as the aforementioned neo-nomad, "one of the growing number of people who use digital technologies to allow them to work from anywhere, living with 'no office, colleagues who are largely engaged with online and often a number of overlapping projects to be juggled and managed at the same time'." Now, he is taking the concept one stage further by selling his house and embarking on life as a "digital bedouin", seeing how far he can get with a laptop and an internet connection without having to be rooted anywhere: home or office. He's giving it a trial period of a month, to see how he can use the technologies around him to support his existence. If it's the kind of life that interests you, there are some useful pointers in Bill's post as to what devices to use and storage/back-up systems to prevent your very being from vanishing into the 'cloud'.
Or, you could just go to China instead. For that, you'll need a bit more than a laptop and an internet connection, it seems.
