I think the first operator to incorporate WiFi in this area, was Stagecoach Fife in its routes to Edinburgh, Glasgow etc; and that was about 2008.
I tried it out in March 2010, as an experiment, on an Edinburgh-bound service.
I have similarly tried it on its longer-distance service to Aviemore, the bus carrying on to Inverness, about 2011.
So public road transport WiFi in the east of Scotland is generally widely available.
Rail is not so well covered.
A driver mentioned that he had noted one passenger using hair straighteners or similar ion the on-board Maiins supply.
