Windows Phone Summer Break
If you needed more reasons to get interested in Windows Phone development, let me throw this your way:
Until 08/27 you only have to pay $19 (normally $99 for individuals and companies) to start publishing your app in the Windows Phone store. If you want more information just follow this link or go directly and register here.
If you already downloaded the SDK and have some cool ideas in your mind, this is the perfect time to show the world your hard work.
