I was getting frustrated with the fact that Emacs default modes didn’t handle long lines well.  This is fine for editing code where I keep all lines under 80 characters, but for editing documents it was a pain.  Going to the end of a line <Ctl> + E took you to the beginning of a paragraph since Emacs was concerned with the actual line of the file, not the displayed line.  The solution is longlines mode. This mode breaks up long lines for editing, and still saves them as a single line.  I used to have to download and install it.  Now it is bundled with Emacs 22.  Nice.
