I personally use Zoom about four times a day on average. We have our boardrooms set up with Zoom Rooms and we have it rolled out throughout our organization. We use it for video interviewing remote workers as well as huddles and bringing our teams together.
Compared to the classic room solutions, it's far more reasonable to get into vs spending $7000 upfront on some hardware that is always glitchy. I can also just call someone via the contact list or by choosing their room rather than trying to type in an IP address
