Thankfully our IT systems were pretty well established from day one, so it was possible to do so, although at that stage, all I really had was my laptop. Since then, a fairly large amount of additional kit has been organised, and I've done a pretty good job of colonising the study. I now have a docking station for the Surface, to which I've been able to connect two external screens, wireless keyboard and mouse, a couple of little external speakers, and I'm connected up to the home printer. I've even taken delivery today of a new office chair.
It goes to show that there is definitely some mileage in doing some more remote working, even once we're allowed to go to the office again.
