The wakeup call folks asked if I wanted a fifteen - minute reminder call , and I said yes please , which turned out to be wise . I started my day at nine and walked through the hotel complex to the conference center around ten . I registered , and got the geekiest badge ever . It has a microcontroller , a capacitive touch sensor , an accelerometer , and a bunch of LEDs . There 's actually a programming contest to see who can make the badge do the awesomest thing .
Question: Why did the folks asked what they wanted to give me ?
The answer to the above question:


They wanted to give me a fifteen minute reminder call .
