I know most/.ers don't RTFA, but not even reading the OP.....wow. Sorry, thats probably uncalled for. Anyways, it is being "spread" by people downloading it from alternative app marketplaces.
Get real you AC. The real world is a lot more complex than the "utopia" you seem to be in. I was just stating the fact that the choice to use a particular OS is usually dictated by the requirements of the application for a needed system.
Windows is such crapware, as so many of you think, why don't you guys all get together and write an emergency management system that runs on a Linux distro? Now I obviously don't know for sure, but it seems likely the reason they are using Windows is that their application is written that way. Take a way the need to use Windows before bitching and moaning about them using Windows.
