we needed a command line network debugging tool/app for some customers to run. turned out that Go's ability to cross-compile and build single-binary apps on mac/windows/linux/android/freebsd was just perfect for that use case. single code base, easy build management, single-file .exe distribution per platform, same app experience on all platforms for customers. A+.
