Might be interesting (and someone's probably done so in the past) to look at the user agent info and see what people are actually using

That would be very interesting, especially plotted over time!

I know it is totally different and not really comparable, but one of my company's websites is currently 62% mobile visits compared with 54% in September 2018. The other main site we have is 87% mobile. I have no previous data to compare as it only went live earlier this year. The high mobile on this site is probably due to driving traffic from Facebook with paid advertising.
