I shot quite a lot of pictures with my K700 Sony Ericsson mobile in China - hundreds of them - and while the pictures aren't exactly high quality, the portability and anonymity of the phone allowed me to capture scenes that I wouldn't have been able to with my Canon.

The pure, unfettered joy of alcohol.
Since we often spent several hours in taxis during the day, I'd stick the phone out the window - or in - and click away, much to everyone's annoyance.

Our cabbie, caged.
