I was reading a story on Lifehacker today about how to amplify your smartphone by using a drinking glass. The author wrote that this is a great trick for those using their smartphones as alarms.

That made me wonder: Do people still use dedicated alarm clocks, or is this something else that's gone extinct because of smartphones?

I currently use my iPhone as my alarm clock, and before that I used my cell phone. It's easy and convenient to use your phone as your alarm as it's on anyway, it won't go out if there's a power failure, and it most cases you never have to worry about setting the time on the clock--which 9 times out of 10 was a really tedious and complicated process.
