I'm gonna Tarantino this one a little bit and start in the middle so I can set up the video below. The activity tracker I've been trying out is a Polar M400 GPS running watch. It counts my steps and tells me how many calories I've burned and all that jazz, but another one of the watch's features is that it beeps at me when I've been inactive for too long. That got me thinking: What if they took it a step further and gave the watch a little attitude?
