Not that am aware of, but I've never found it to be a limitation.

Two main reasons: first one's effort; to select a line I just have to click and move down a tiny bit, as opposed to click and move all the way to the right. Second one is when copying multiple lines where start of the first line doesn't start at the left; you'd have to copy the whole line and trim.

Again nothing earth-shattering but enough to annoy me immensely

You mean you never run *nix as a local OS?

Correct. I play games on my desktop so windows is pretty much a requirement, and laptop is a company machine with a standard windows image. I have run a linux GUI at times but never found a reason to use it over the windows one.

I don't have the aversion many people seems to have to scroll bars and horizontal scrolling

I find it rather convenient to be able to keep everything visible on the screen at once; with 4 windows I could get 45 visible columns each, which would hide a lot of information if it doesn't wrap. Different use cases again I guess.
