The only two syncronized address books were the Palm's one and its desktop counterpart.

Today all these address books are aligned thanks to iSync. It's something I've been dreaming of forever, it's good to see technology finally catching up.

As an added value of having a bluetooth enabled phone, I can control my Mac with my phone (thanks to Salling Clicker). I have just installed the utility and clicked trough all slides of a presentation with my phone (Salling Clicker allows also to control iTunes, the DVD player and several other applications).

And when I receive a phone call, the caller's name appears on my Mac's screen, I can send SMS directly from my address book, and I guess there are still several cool interactions that I have to discover and many others that have to be invented.

All pieces are joining, very, very cool.
