My problem with copying & pasting are the media breaks: I have to format the patch, make sure it doesn't get mangled by some auto-wordwrap, trailing whitespace deletion, etc., and then paste it in or upload to a web form. git push ensures that I don't have to worry about any of that because the patch is an opaque "blob".
