Go is cool. Go isn't too fast and doesn't have as much tool support as Java/Xtend. Go may be great if you're doing network programming on Linux. Like many tools originating from Unix environments, the cross-platform support may not be a top priority.

You're set as you already use Eclipse. :-)

Go's cross-platform portability is quite good, writing portable Go code is infinitely easier than writing portable C or C++ code, and probably as easy or more than Java.
