Microsoft has just today released their "band" which appears to be a fitness/health band, watch and notification center for your Windows Phone (Reminders, email notifications, social media notifications, who's calling, weather etc) and it even allows you to interact with the Microsoft Cortana voice activated assistant for taking notes or getting driving directions.
Looks like it also has an app so that it works with phones for people who have a phone from "those other manufacturers" as well but you miss out on some features if you don't have a Windows phone.
I haven't looked into the details yet (like availability dates for Australia), but the following screenshots look interesting and more information is available at http://www.microsoft.com/Microsoft-Band/en-us.
