Microsoft Wireless Display Adapter which retails for S$110 in Singapore can be mistaken for Microsoft’s version of Google Chromecast. In fact, both of them are quite different. Despite their differences, I don’t think their prices should vary that much. So I am not too sure why Microsoft would price the Microsoft Wireless Display Adapter at US$59.95 when the Google Chromecast is only retailing for US$35.
Microsoft Wireless Display will work with Windows devices and Android devices but not iOS devices, whereas Google Chromecast will work with Android devices and iOS devices but not Windows devices.
