Simple: Cygwin provides Linux-like functionality without the need to install software that relies on device drivers or requires administrative rights, or to install and boot a 2nd operating system. Cygwin works within your existing Windows file systems. It is much simpler and requires less resources to open a Cygwin shell than to boot a 2nd operating system.
