I am thinking of switching to a supernote which allows me to write on a paperlike surface, but mainly because it is free from distractions and notifications on an ipad.
i mainly like the idea of a blank canvas and writing and rearranging thoughts on that canvas - which pen and paper do not allow.
He wasn't saying "buy a fancy pen, it's better for your brain".
The positioning is "every time people hear that I write on paper, they come up with all these reasons why it won't work for them (crap/smudges/etc). These are the things I do so that's not a problem for me"
The part about choosing paper is about fountain pens being blotchy where better quality paper helps.
You can write with anything and on anything, but just like how it is much more enjoyable to type on a fancy mechanical keyboard it is more enjoyable to write with fancy fountain pen. Although I prefer gel pens since they are just easier to have a bunch around.
My guess is cheapest versions of each are the problem
Fountain pen + fancy paper sounds like I am tied to a desk again. Stephenson is probably doing way more intense sit down grind out some pages type writing sessions though.
