On the road and need a wake-up call? Have no fear, Wakerupper is here! This free site lets you choose the date and time of your call; you can even type a 140-character message and Wakerupper will translate the text to speech and read your reminder to you. I gave it a try and it nailed this 100%: "This is a test message. Don't forget to pick up Tyler."
