Not only did it work great for emergency situations (I ran Ubuntu MATE as well) when I needed to SSH into machines, check stuff on Datadog, edit code to make a quick fix, push code to our K8S environments and more, but I actually found myself frequently at coffee shops and bars coding away happily on it. It brought a certain amount of freedom and cool factor with it. It was a delightful little device with a very sharp and crisp screen, a surprisingly useful keyboard that combined well with my i3 environment, that I could actually be productive on (save for running our test suite which took around 30 minutes and sucked the life out of the battery). It also got a lot of onlookers asking questions about it, leading to those ever so fun random conversations that can lead to night long friendships over wine and coffee.
I genuinely miss it and will probably pick up another one now that I just got hired as a CTO for another project with equally demanding on-call schedules and uptime requirements. Although I don't drink anymore so none of those fun conversations. Ce la vie.
