Hopefully not thread drift, but this is similar to the issue my parents in law (85 years old) are having with their car. It's a new Cadillac and has a touch screen interface for navigation, audio, aircon and virtually everything else. It baffles them totally. They want chop it in for a car that they understand, but nearly everything new has this technology. Unlike me, they won't consider a 7 year old car with buttons.
I'm happy with touch screen phones, tablets etc and hardly use my traditional desktop and laptop Macs any more.
The thought of a bluetooth DCC system certainly is attractive, although I can see there are ups and downs.
Now, how about 'Siri, throw points 1 and 4 to the main line, blow the cylinder drain cocks on the 2-6-0 and accelerate the train to a scale 25mph, stopping at the next station'?
