No. 7. Sleep Analysis Doll
Sure, it seemed like you slept OK, but how will you know for sure? Short of talking to a horrifying sleep analysis doll, you'd have no way of knowing, which means it's a good thing that just such a doll is now available on the market.
With its 6 sensors and vocabulary of 1200 different sentences, the doll is capable of determining a user's sleep patterns and then badgering you when you don't stick to said sleeping patterns. So that night that you have insomnia because you're nervous about an important project at work will be made even more fun with a disturbing doll berating you for not being asleep. Good times. And a normal person would buy this why?
