I keep dotfiles and configuration scripts on GitHub. Use a password manager for any kind of authentication. An MDM takes care of application installation, apart from some of my own idiosyncratic needs, which I install for myself - they're all OS or direct-download, so no appstore involved. Dropbox handles files.

I got to stress-test this a few weeks ago, when I stupidly left my laptop at my dad's house, three-ish hours away. It took me far less time to get myself set up and fully-productive on another machine than it would have to even make the one-way drive.

My only real frustration so far: installing all of the SublimeText packages I've come to rely on. Once I get my my other laptop back they (or at least their configs) are going into git as well.
