Andy thanks,
Agree on all your points.
High quality video on web conferencing and the TelePresence experience make face-to-face meetings more of a luxury than an absolute necessity.
According to our internal Cisco statistics, the average meeting involves 4 people, where 2 of the participants are joining remotely. Video is of huge value.
Considering saved travel times - even just the walk between rooms on a campus - video as part of a complete digital workplace, is a big boost to productivity and effectiveness.
