For me the biggest two are:

1. I used my (relatively short [20 minutes]) commute to listen to music or podcasts and get some separation between work and home.

2. A lack of analog whiteboard-style collaboration. We use Miro (and it’s pretty good once you get used to it), but even though Miro is better for some use cases, it’s way worse for others. The high-bandwidth, three different people are all holding a market and sketching ideas together simply doesn’t have an adequate replacement in a remote world IMO.

Edit to add: 3. Group meals (mostly informal lunches) builds a sense of camaraderie and understanding of your teammates in a way that Zoom never will. I treasure the random nerdy conversations over lunch tables.

Overall, I love remote though and expected I’d hate it.
