This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
Go was originally designed as a systems programming language to succeed C, so there's nothing you can do in C that you can't do in Go---and Go is easier to write and maintain and is relatively speaking a safer language. However, right now Go doesn't have strong support for GUI programming or for mobile programming. It can certainly be used for low level systems programming---at least on Unix---but I'm not sure about device drivers.
