IE=edge simply tells IE to use the last version of the rendering engine.

It's documented here, just like the less useful (in my opinion) IE=EmulateIE8.

IE=edge helps you avoiding some "compatibility" behaviors. It makes IE9 more compatible with other modern engines.

See this related question for example. I always start my HTML files with

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
