Face-to-Face conversation can also happen remote synchronous.
In addition, while whiteboards can still be nice for certain things, over the past few years I've also come to realize that collaborative docs (e.g. Google Docs) are actually as good or better for a lot of purposes.
Not sure if this is due to something I lack, or if (some) people are less attentive/perceptive/focused in phone/video calls.
- it's easier to be distracted - it's harder to read gestures and expressions, worse with group meeting - with normal keyboard and mouch / touchpad even touchscreen, it's harder to sketch - while small, there is latency and it can be distracting enough
IMO it's easier if the communication is one way at a time, not both at the same time.
