The powerful .NETMF on your wrist! Meet the Agent
So if you've been under a rock lately, you might have missed this little phenom known as KickStarter. Well today you're going to want to check it out. Secret Labs, the folks who brought you Netduino (hey, I'm wearing a Netduino t-shirt today, what a coincidence) have teamed up with a watch maker in New York City (SL is based there as well) to bring you Agent! http://www.agentwatches.com/
So what is Agent? I could write this whole long blog post about it, but you'd be better off just reading the KickStarter page.
Basically though, it is a .NET MicroFramework powered device, with long battery life, and awesome features, that will allow you to easily develop for the watch, using the Microsoft tools you already love (Visual Studio 2012).
The project is in a funding phase right now, but I believe the SDK will release by the time the KickStarter campaign ends.
So get to it, fund this project! http://www.kickstarter.com/projects/secretlabs/agent-the-worlds-smartest-watch
