What’s the next device in your home that needs to be connected? If you said “The toaster!” well, yes, but hang on, Mr. Nibbles. First let’s gets you the Fitbit Aria ($130), a Wi-Fi-enabled scale that uploads information to your private account each time you step on it. You can then monitor your progress at Fitbit.com (“Hmmm. It says I gained a pound, but all I ate yesterday was that entire goat.”) track your trends, and compare your stats with friends and family. Next year, we’ll get that toaster of yours to run social media apps. That’ll surely be a great step forward for society.
