I do the same, but I've had trouble with the overhead of virtual machines (admittedly on an older laptop). Have you not found this to be a problem at all?
As deployments get simpler and the usefulness of Ansible for server config declines, I'm thinking about abandoning the VMs and going back to running things in OS X.
Not myself. The VMs are never doing anything so taxing that they incur significant overhead. I can regularly keep 3-4 running concurrently without an issue.

I don't ever see this being the case. Configuration is becoming more challenging, not easier. Even if you use a tool like Docker perfectly for all of your services (which is ironically very hard without some kind of CM tool beside dockerfiles), you still have to: install packages, change configuration files, run commands, enable services, change permissions, change firewall rules, modify DB users, manage SELinux, setup log file rotation...
Servers are hard to set up and maintain in a coordinated fashion without some kind of CM tool. And while PAAS providers can handle quite a few lightweight services without requiring you to use any CM tools, there comes a point where they no longer scale the way you need them to, and you're back to provisioning VMs or even bare metal.
I've had this setup for 2 years now. No issues and I get to use sublime to edit files locally while they are shared with the VM.
