Just received a text from my mate Neill (another mac user - we both went to the Mac OS X launch at Micro Anvika all those years ago). He's just bought a Bluetooth adaptor for his G4 and has found out that you can text and talk to people on your bluetooth mobile through your Mac. This is a real thumb saver as you type out text messages on your keyboard. Incoming messages appear on your screen.
Not even I knew that. Well done Neill!
