Jawbone UP - a personal trainer on your wrist
Wow, this little activity monitor looks like a game changer. It tracks all of your daily activity (and any slugfest couch-y segments too). Even gives you little vibratory reminders to move if you've been sitting for too long, has a smart alarm to wake you when you're out of REM sleep, and tracks how your food choices affect the way you feel. Pairs with iPad, iPod touch and iPhone. And an 80-minute charge lasts 10 days. Available at Apple stores for about $100. More info at Jawbone.
