Seen in Marseille, France last week-end. An interesting occurrence of very close proximity between a human being and his cell-phone. Various remarks here:

The user seems to have a certain level of trust in leaving his phone like this, while being asleep. Thieves can take it readily (I've often seen people's phone being stolen like this in café).
The contact of the phone on the human skin is definitely useful to know is someone calls you or if you received a message (through vibrations). It's also possible to have a quick glance to the screen, in case it's needed. The effort to interact with the phone is then quite low.
Some people fear being so close to their phone because of waves/electrosmog, this guy doesn't seem to mind about it.

Why do I blog this? documenting practices from the 21st century, surely some material to be reused later on in courses/articles/speeches.
