Phone Valet is the best gadget I've purchased since TiVo. Why I love it:

1. Voice dialing - It is so cool to use your voice and just say "Call Jolie". Phone Valet then displays an alert that says "Pick up the phone to auto-dial Jolie". I pick up the phone, the alert goes away, the number is dialed, and that's it.

2. Call announcement - when someone's calling in, it displays, in nice big letters on my screen, who's calling, and speaks the name too.

3. Integration with Address book - It's easy to set up Phone Valet because it imports from Address Book. I still wish I didn't have to maintain a seperate contacts database though. In an ideal world, contextual menus in Address Book would fully support Phone Valet's features.
