Ask HN: Moving from OS X to a remote virtual dev environment

I'm currently running a 2013 Macbook Air for mostly ruby web development work. I've been wanting to upgrade for a while but I'm just not that fussed on Apple's latest laptop offerings. As I work from home I don't really need a grunty laptop anymore.

So far I've been managing my Air's 8gb memory limit by running work's dev vm on a headless PC so I'm considering upgrading that PC so it can handle more VMs to try get a fully remote development setup working.

Does anyone have any good advice on a fully remote virtual dev environment?

My big question is how others best to handle working with code remotely on a VM. I know some people who ssh in and vim away but I'd rather work in Sublime if I could.
