Yeah, I've got my laptop running LMDE now (Linux Mint Debian Edition) and it's mostly pretty nice.
I did run into some things while installing that you'd have to be techie to get past. There was a thing with Secure Boot and a thing with a WiFi card, where I had to resort to trawling forums and blogs for other people's solutions.
But since it's actually been up and running, I wouldn't hesitate to recommend it to an ordinary person for all the normal kind of stuff.
Dragon (speech to text) had been the last thing keeping it on Windows, because these days my fingers get iffy if I type too much. I did think beforehand that I might have to keep that going on top of a virtual machine. However, Talon seemed worth a try, in its dictation mode. And after a couple of months of adding to my corrections file and getting used to its conventions, I reckon I'm just as fast on that as I used to be on Dragon.
Still need Win or Mac if I want to run Dorico (sheet music creation). That's not an everyday task for me, so doesn't have to be on the laptop.
