The ‘Live’ iso enables a Raspberry Pi to be tried or installed in a virtual machine. or burnt to a boot USB It obviously has a few hardware limitations (e.g. gpio), but if you change the screen size (xrandr -s 1920×1449 for example) then it makes a better development environment for playing with Python, Minecraft etc. You may prefer lxrandr from the command line.
It also provides an Android development environment but I have not tried that aspect.
Others have reported issues with vmware tools but that ran without issue for me. Others have had problems with virtualbox, but that is untested by me.
