Re: re MSRT
Additional. OK I was a bit biased against Mint 19.1 because of its piss-poor performance in a Virtual Machine. Your post prompted me to go one step further on a Dual-Core Toshiba Satellite laptop and upgrade from 18.3 to 19.1.
I had no problems doing it and I find that the resulting performance is quite acceptable. I'll still stick with 18.3 on the others for now, but at least I know I can move up should the need arise.
