After being pleasantly surprised with the very easy setup of iSync with my Bluetooth phone and iCal/Address Book/iGTD, and then discovering how mind-numbingly easy it was to transfer photos between my phone and the Mac, I never realised there was another piece of subtle phone/Bluetooth integration sitting there waiting to leap.

You can use Address Book to send an SMS. In fact, it receives SMS’s too, and can store them as notes against the associated contact, dial numbers and log received calls. If I’d only realised that I needed to click on the bluetooth icon on Address Books toolbar, too subtle for me!
