We got some good mileage out of them during covid as well. My WFH setup early pandemic had the large portal as my primary visual conferencing setup - it beat the hell out of a webcam on top of a monitor.
It's disappointing that 6 years later there's still no solution. The window has passed for my kids - but it would have been really nice to be able to have large format TV based video calls with the grandparents. I tried to set something up with a laptop, but it was always too janky and fiddly to work well.
