BluePhoneElite

Speaking of SMS messaging via your Mac, make sure you check out BluePhoneElite,
formerly known as BluePhoneMenu.  It's currently free
(translation: in beta with a purchase link announcing that purchasing is not yet available) and does quite a nice job of coordinating SMS
communication between your Bluetooth capable phone and your Mac, as well as serving as a rather powerful call center: "Dial, answer, hang up and hold calls with the touch of a button. Both incoming and outgoing calls are saved to a call log that includes the time, date and duration of the call, the phone that was used, and whether the call was answered, missed or ignored. You can even add notes to a call and export it to Apple's Address Book or iCal!" Pretty snazzy!

Thanks, Judith!
