Stumbled across this video from Google:
If I only had an Android phone, I'm pretty sure that I would get that wifi weighing scale and pedometer. Actually, there should already be a pedometer app by that time.
I think autosync is a good thing. I used to (because I haven't been running in a while) really appreciate Nike+ tracking my workouts. A visual representation (especially using graphs) of your workouts can actually encourage you to push yourself more. Seing how much (or how little) you run at x pace through y distances and z times plotted in tables, graphs, or even through a "wall" can help you plan and set goals better.
If you think about it, it puts the work of a personal trainer into your hands. It's a great idea.
Of course, this is another example of how Google runs our lives. But again, I'm not complaining. I really am just waiting for Android to match up to the flawless UI that my iphone provides. I digress.
For now, I am stuck with Nike+ (which by the way is connected to my Apple devices) and I have no way of monitoring my weight. That still works, but I'm sure I'll get more progress if more of my activities were tracked.
What gets measured, gets done.
