I'm using a Chromebook that I like pretty well as a fancy terminal. A setup that interests me is Kenn White's at https://blog.lessonslearned.org/building-a-more-secure-devel... -- keeping it out of dev mode and using Android apps to fill some gaps.
Big blocker for me starting over and doing that is VPN support. I have to decipher how to convert my work's OpenVPN config to Chrome's ONC format.
