I have lots of devices and those I use almost daily include: a smartphone, tablet, chromebook, laptop, desktop and two home servers, not to mention a raspberry pi doing odd jobs. I'm forever grabbing one or the other depending on the need and situation and it wasn't long before I realized that I needed some way to sync at least some key files to all these devices and I've used lots of different methods to do this over the years. Lately its been a locally hosted git repo. What are you using?
