better video chat with screen share abilities and decent noise cancellation. We tried Skype, Zoom.us, Slack video, Google Hangouts and WebEx … they all have issues and none of them work reliable enough even with decent internet connections across all three major operating systems. If we would need custom hardware for that: we'd even buy it, a good high quality webcam and headset would go a long way.
I honestly can't believe that's the biggest problem we've had so far, other than that it has actually been a smooth ride.
