Earlier this month, Facebook bought WhatsApp for $16 billion in cash and stock, with another $3 billion to be vested by its employees over the next few years. It turns out that the total $19 billion figure for the mobile instant messenger is one of the biggest acquisitions of the year — and one of the biggest Silicon Valley has ever paid out.

So what's cheaper to buy for $19 billion? Iceland is cheaper to buy than WhatsApp, with a gross domestic product (GDP) of $13.7 billion for 2012. It's not surprising considering less than one-third of a million people live there, but still an impressive financial feat nonetheless. You could even throw in a Large Hadron Collider with it.
