I liked that one, too, but for an additional reason.

Typing that first character on the page reveals the problems you didn't even know existed. You don't have a keyboard. You do, but it's not plugged in, and you have to move an unexpectedly heavy bookcase to reach the USB port. You need to learn Dvorak. You don't have page-creation privileges and need to open a ticket that will take a week to resolve. You can create the page, but nobody else is able to read it because their machines aren't allowed to install the version of the PageReader™ plugin that your page requires (and you'd need a VP exception to downgrade your PageGenerator™ toolchain to their version). And so on.

All these are silent schedule killers that reveal themselves only once you've shipped one full development (and deployment!) cycle. And as ridiculous as these example problems seem, they're not far from reality at a place as big and intricate as Google.
