Regarding lifelogger, I like that term!
I can envision using this during travel. We recently came back from Europe and it would be lovely to have a record of where we went, for how long, etc. That would be really awesome. I can see myself using it for that kind of purpose. It's also one reason that I love using my iPhone camera during travel instead of a regular camera. iPhone camera records the geolocation which to me is important during travel because in time, I'm going to forget where exactly something is and even what city it may have been taken in. I know, some standalone cameras include GPS but I think that's few and far between.
