What does your mobile say about you?

I was looking at some referral data on my Sitemeter today and stumbled onto these three blogs, apparently by three Telecom Italia employees (I'm guessing R&D people) who are engaging in the MobiLife Project, driven by the Context Watcher application. Just for the record, I'm going to get a haircut in a moment, and I expect to be moving at a maximum speed of 3mph. I will take no pictures at the barber shop. When I return my hair will be shorter (15%).
