After years working with two computers, the best setup I came up with is making my main computer run Windows with Remote Desktop and connecting to it via VPN. Then my portable computer is just an iPad running the Remote Desktop client. Excellent battery life. As long as the internet connection is reliable, everything works perfectly. On my home computer I just connect in the same way. Not having to duplicate the dev environment saves me a lot of time, the only sad thing is I need Windows (and yes I’ve tried many other remote access solutions).
