Not that installing Linux is difficult, just that A. I suspect we'll see a lot more people on Linux computers, especially in the developing world, and B. beginning programmers should be introduced to the concept of Linux as a programming environment
Go is dead simple to install to Linux via either binary or source. Even building it from scratch on non-standard Linux systems like embedded armv5 systems is easy. Basically if you have a non-broken gcc already, go will build just by invoking one single shell script they provide.
I write the code in Windows (Sublime Text 2), compile in Windows, but target GOOS=linux, GOARCH=ARM, GOARM=5 and end up with an executable that I can easily rsync and run over on the ARM device. The cross-compiling available in Go is much easier to setup initially than the usual situation of having to build an entire toolchain for your target.
