I've been remote for two years and don't want to go back to the daily commute. I've been happy to sacrifice one room in my home to be an office in exchange for not running the traffic gauntlet each day. The one thing I still prefer in person is whiteboarding. We have good collaboration tools but none of them yet match the efficiency of people in a room together working on a common whiteboard. There are digital whiteboards that might fill this niche but currently they're too expensive to distribute to entire teams. Maybe over time this will change.
