The idea of the windows installer is to make it easier to setup the Xith3D development environment in windows. It's not a hard task on any OS - but I've been told that some windows developers can be more lazy than others and just want a turnkey solution.
Not tainting the poll at all!!! If you vote yes now you're either "stupid" because its not a hard task or "lazy".
Not all developers are as clever as you lot, "stupid" might well just be inexperienced.
Not all developers have all the time in the world, "lazy" might well just be using time wisely.
However, I of course don't care
PS. This is almost a direct parallel to the Linux<->Windows debate that raged for weeks.
