Things are pretty decent for me.
When the decision was made to work-from-home, I just used my work laptop. A few days later I drove to the office and grabbed my monitors, keyboard, mouse, and various other odds-and-ends. I now have the same setup at home as I did at work. I already had a home-office set up, so all I really had to do was shuffle things around to make room for all of my work stuff.
I did have to buy some stuff to make the home office more usable though. I've added a keyboard tray, cheap portable air conditioner (my home office is west-facing, so afternoons can get quite toasty), and a cat hammock for the window. Of all of those, the cat hammock was the biggest boost to my productivity since it keeps the cat off my lap/keyboard.
I went from an open plan office with 250 people (across probably a dozen departments) to my own private office with a window that opens. My commute went from about 2 hours per day on public transit to about 1 minute per day. I haven't had to buy lunch (or been tempted by vending machines) in over three months. I can open a window and smell freshly cut grass and hear birds chirping.
Socially, I'm actually keeping in touch with friends slightly better than I was pre-lockdown. On the other hand, I'm not seeing friends in person as much as I used to and I'm not walking nearly as much as I used to - these things are slowly taking a toll. My volunteer gig also completely shut down, I really miss that.
I'm not looking forward to going back to the office. I'm not looking forward to wasting 10 hours per week sitting on a bus. Actually, the chances of me being willing to take the bus when there isn't a vaccine available are pretty slim, so that will turn into about 8 hours per week of driving, not to mention the added costs of gas, maintenance, insurance, and possibly parking - none of which I'm looking forward to. My current car is a pig on gas, which is fine since I'm not using it for commuting, so I may need to replace it to make driving to work even a little bit reasonable.
