As with most 'smart' devices at the moment, the Hapifork is limited by syncing and charging, as well as our natural ability to ignore good advice from a nagging technological snitch.

After a few meals, I was surprised to find myself being more thoughtful with my eating, placing my fork down between bites. It didn't always stop me from wolfing down dinner after a long day at work, though — I was hungry. When my hunger outweighed my concern for my eating speed, I ignored the Hapifork’s vibrations and its disapproving red light.

I wonder if they'll do the same for chopsticks?
