Does anyone have practical experience of Gnirehtet?

After being frogmarched (kicking and screaming) into the 21st Century by the young women (nieces and colleagues) in my life:

I now find myself trying to grapple with what seems like a tiny and extremely fragile piece of kit. It feels as if it would break if I look at it the wrong way and the screen is a bit of a change from the monster I have attached to the main Linux box.

Bah, humbug.

I have been trying to reverse tether the 'phone to the U-box (currently on MATE 18.04 although I quite like the look of tomorrow's release).

The smartphone's on-line performance can best be described as anaemic. This is ridiculous when there is a nice fast connection only a few centimetres away.
