How about making a wall clock or desk clock which has a way of synchronizing with your calender and reminding you of your events.

The clock can have a Bluetooth which can then be accessed by a custom mobile app. The app would synchronize with an existing calender on your phone. The clock can have a scrolling led display which can display the headline of your event. The clock can have a silent mode, in which case the screen will flash as a reminder. The clock can have a memory for 1000 events, this way once you program it, you don’t have to synchronize it often.

This way you don’t have to set alarm’s ever, the clock will be smart enough to wake you up for your first appointment of the day.
