The Super NES was shaped in order to prevent spilling accidents!
The Super NES is one of the most successful videogame consoles of all time, and the platform on which many of the most famous and critically acclaimed games of all time appeared. It was a follow up to the original Nintendo Entertainment System that had been released in the mid-1980s.
If you're old enough to remember, the original American NES had a very boxy design, with a flap that you would open and you would insert the NES cartridge horizontally. The design had an unintended flaw. People would rest drinks and food on top of the flat top of the NES and they'd be spilled all over the console, breaking it.
Nintendo sought to fix this with the Super NES. Instead of a sideways loading tray, they created a top-loading bay, that had a curved shape. The shape was designed that way to be inviting and also to prevent people from resting liquids anywhere near the console.
The Japanese version of the NES (called the Nintendo Family Computer or Famicom) did not have the boxy design of its American counterpart. When the Super NES (or rather, the Super Famicom) came out, the redesign was not as dramatic as in North America
