I live on a big island in the southern hemisphere. Working remotely on a Linode is painful due to latency even with mosh. I tied Fremont for ages but the latency was too much so I moved to Tokyo which is a little better but I still prefer to work with a VM locally. Vagrant gets the job done but I would prefer an alternative.
I don't like Ruby. I don't like running virtualbox when I could be running an lxc jail with something like docker. I think I will be ditching OS X and moving back to a Linux desktop as soon as I find the right laptop.
