You've never wanted to edit text/code on a computer that isn't yours before? There are a lot of cases where I can see this coming in handy for making quick edits as an IT professional, especially in cases where I need to mess with a slightly complex file on an end user's machine but don't have the time or desire to copy it back to my own. It's a tool, you don't have to use it.
