Yeah....,for those who are unaware with JIT (Just In Time) concept by Martin Frey. Check him out on http://www.youtube.com/watch?v=-6dSQLoQOLM or just type "Just In Time" on "Youtube" to get intel about this watch. This prototype or idea and/or watch came out perhaps years ago but..., I'm doubtful about it coming into fruition! Now..., consider JIT's watch concept and the N900 hardware similarities..., why not build an app similar or based off JIT's watch for the N900?!? Both devices have the prerequisite ( GPS, Bluetooth etc,etc) or capabilities and it being a app on the N900 is rather..., practical in contrast to a watch. Any feedback?
