@kfield: Well if you are competitive (i guess i should have said SINCE you are competitive), FitBit is for you!
I'm wearing mine as we speak -- I love it -- it was the fact that I was wearing it yesterday that prompted me to walk from one end of Terminal D to the other end of Terminal A at Dallas airport yesterday (rather than catching the monorail) just to get the "steps" added to my FitBit chart.
I remember going past gate A40 on my way to A9 thinking "not far now... almost there." Of course I thought something else (like "Oh dear" but worded differently) when I finally arrived at gate A9 to discover that they had changed the gate to A38 (LOL)
This story reminds me of a time my clothes really did shrink: I cam home from school only to find my brother and sister in the laundry room, each tugging on the sleeve of my favorite sweater, which they had shrunk to Barbie-doll proportions in the dryer.
