Amiduos is a $10 app that lets you run Android on a Windows PC

At just $10, [Amidous] is pretty affordable for a full-featured Android emulator, and it’s based on Android 4.2.2. An update to Android 5.0 Lollipop is due to be released this month, which means you can potentially run a newer version of Android on your Windows PC than the versions found on about 90% of all Android devices. – Zach Epstein, BGR
