I have also heard that it can tell time, but that feature's a little harder to find than the rest.
Recently, I uncovered another of Garmin's many widgets, one I was not aware of before. Garmin is also an effective babysitter.
I came home from a run, and Jack's desire to be entertained didn't mesh well with my desire to sit on a chair and drink Gatorade. Then, I had a holy Garmin vision (praise be thy name), divine inspiration if you will.
I put Paula Garmin on Jack's wrist and told him to run around the backyard so I could see how fast he was going. Jack thought this was the coolest idea ever. I gave him my iPod (tuned to the Captain Cubtastic mix) and added a headband to hold in the earphones. The result looked like this:

Garmin then proceeded to entertain Jack until dinner time. He raced around the back yard, creating obstacles for himself, and singing along to his music (particular favorite: "We Will Rock You"). My job was to occasionally throw out some encouragement: "You're doing great!" or "Don't stop running" bought me plenty more valuable chair sitting time.

His average pace was 15:something, probably slowed by the zillions of times he fell, the one time his shorts fell down, and the times he spent hiding behind a tree.
Now we just need Garmin to come out with My First Forerunner, because as this picture of Jack after the Bix illustrates, my boy loves to run.
