- Big bright LED ring around the outside that glows red or green to tell you if the room was available. This was very useful when performing one of the most common big company rituals, craning your head while speedwalking to try to find a free meeting room.
- 1-tap to book a room when you found such a free meeting room. They listed a bunch of common durations, including ones that rounded up to the next half-hour/hour.
- The "outside" Gizmo is integrated with an identical Gizmo inside the room that controls the VC equipment, providing a consistent UX. This is something I only appreciated after leaving: at my current company, the two are sourced from different companies and don't integrate -- you have to exit the meeting room and use the "outside" tablet to extend your meeting or check in, for example.
- When a meeting was running over and people checked in on the "outside" Gizmo, a loud ping sounded on the "inside" Gizmo to tell everybody to GTFO. This was not always successful.
