WinArosLight is a preinstalled AROS on a HD image, that runs under Windows using QEmu. WinAros Light targets developers, using AmiDevCpp to develop AROS programs. WinArosLight in combination with a program like ultraiso is a nice test environment for those programs. WinArosLight uses the latest AROS snapshot. Other than all that, it's just a really easy way of testing AROS. Download it from this page, 'WinArosLight.exe'.
