Research Study a Success

Well, unfortunately I'm back in freezing cold Brisbane after a nice week in warm, sunny Darwin. The research study was a fun experience. I think it was a "first of it's kind" and there's some great group interaction data, comments on the usability of mobile communication devices for groups, observations about the effects of context on usage and some other cool stuff we're still teasing out.

Many thanks to the wi-fi gurus at Darwin Wireless for participating and putting up with our disorganization a few times. It's great to see mobile device enthusiasts contributing to improving future technologies.
