I know what you're thinking: CES is so last week already. But the lessons of CES will follow -- some would say haunt -- us all year long, so it's worth a sober summary of last week's events. To make this quick, I'll summarize this year's trade show in four sentences. I will then defeat the purpose of a four-sentence summary by explaining each sentence, but you are free to withdraw at any moment. 

1. The Internet of Things is really an Internet of Sensors.
2. Your body is a wonderland.
3. Device makers should invest in better experiences, not better products.
4. CES is dead -- long live CES.
