I think the biggest thing I have seen that is a reasonable use of the tech is game streaming. Stadia, XCloud, Geforce Now.

5G with low latency and unlimited data could be a game changer (pardon the pun) for mobile gaming. It works on 4G. I've tested. But you definitely run into latency issues.

Do you need unlimited data? Gaming is equivalent to streaming hi-def video. With good codecs that doesn't really tax even the low end of 5G bandwidth capabilities. It's really all about latency.

Of course, it's not just games that might be streamed this way. Any computing device could be.
