a couple that have come up a lot in my talks with devs who use the CLI, but don't necessary live in it are: copy/paste, dealing with tmux, getting disconnected, using 'vi' remotely, having to setup prompts/colors/aliases on every new remote machine, editing commands without using the mouse. I'm not saying there aren't ways to do all of this now (especially when you have a lot of experience), but there can be a steep learning curve for new devs.
