I work at my desk all day with my headphones on making it difficult to hear my Motorola V551. I had to turn the volume up and drive everyone crazy with my mp3 tones. This has saved my coworkers! I can now keep my phone on vibrate and catch every call, wvwn when the tunes are cranked way up. The additional features of enabling screensaver and pausing of iTunes based on proximity is awsome. Now when I walk away for that important phone call, I know my computer screen can be locked with my screensaver.

The only thing I couldn't get working was the iChat away message. But hey, that's why it's beta.
