As another commenter, I'm probably at 100s per day.
A reason is that I use i3 workspaces, with each workspace being for different tasks, so I don't want to reuse a terminal that has another context.
One issue with keeping a single shell is that the history is full of irrelevant stuff. If you run commands that take a while and print a lot of output, you want it to be as clean as possible. If I want the beginning of the command, I can scroll to the top, and I don't end up with some unrelated output.
I also take quite notes in vim everywhere, often next to long-running commands, using tmux.
