When I first saw it, I agreed with Ross on this. The second time I saw it once I moved to using Linux on a ThinkPad though, I realized it was a mix of Windows' piss-poor design and Ross' skill issue.
One absolutely crucial thing that Ross doesn't mention (likely because he didn't think about it) is keyboard shortcuts. Consider this: none of us use the mouse in an MMO or something to click on the map or inventory, we just use M or I. Nobody clicks on Tool -> Flip Vertically in painting programs to mirror their canvas, they also use M, or maybe V. But in Windows nobody considers using shortcuts and that's because they can't. Well, they technically can, it's just hard-coded to sometimes very uncomfortable keybinds not mentioned anywhere.
Linux does let you customize it though, down to even single-keys in some DEs. Most programs also have their own shortcuts too, and you can just take some time to tailor it to whatever you need. Once you realize this thing you've been using in a bunch of other places are the way to go, you are going to use the mouse a lot less. Not on Windows though, obviously.
