In watching a video of Horace Luke from HTC talk about the Touch Diamond, he revealed three interesting things bits:

1. By utilizing the phone’s accelerometer, if you flip over the phone when a call comes in, the ringer will mute. Imagine having your device out on a table while at a meeting, and you see a call come in. This is an elegant way to silence the ringer.

2. The stylus is held in place with a magnet. When you remove the stylus while in a call, the phone will automatically launch the notes application.

3. The Diamond was designed initially to be a haptic-feedback phone, meaning that the user would feel a vibration with every touch. The reason they nixed the idea, according to Horace Luke, was because “it just sucked.”
