I use a Macbook Air and an iMac 5K at work. I keep these synced up heavily with cloud-based solutions like GDrive, Evernote, and VPN access to the hadoop clusters I work with.

Config-wise, I just built a shell script that I ran on both machines to install the same packages and libs I use for work.

For my startup, we use something like this https://github.com/thoughtbot/laptop (modified to our specs of course) to keep our machines all synced up. I'm thinking of using Docker or Vagrant to consistently provision machines with regular updates though. This has to be explored.
