I'm into the second week of working from home, which has been a steep learning curve - particularly since I conducted a fairly drastic change of career direction at the start of March.
Right now I'm working in an Ikea Poang chair in our spare bedroom, with my home laptop running my workspace and my work laptop on the floor beside me for email and calendar access. I'm already looking enviously at desks and monitors which would let me work more comfortably, notwithstanding that this is a temporary arrangement. It wouldn't even be especially expensive; I just can't currently justify buying a desk, office chair, monitor, keyboard, mouse and whatever else to make the next few weeks a little more comfortable.
That said, there's a strong possibility that part of my work will move permanently to a remote setup. If that does happen, I'll be shopping for home office equipment immediately!
