That's nice, but the grade school kids aren't in the corporate environment. Most people I support don't have a clue how the Start Menu works. If it isn't on their desktop, then it does not exist. Shortcuts and pinning are the only way for them to be able to launch applications. Even for pros anything beyond a handful of applications can make the Start Menu difficult to navigate quickly. Search and easy to get to icons are a good solution.
Why assume that my statement precludes actual office workers? It's my experience that people use the start menu -- especially when their desktop becomes so cluttered its useless (much like the start screen tends to get). When you know specifically what you want the start menu is a better way to go IMO. If you don't then search becomes your friend.
