People wanted to see their toast going brown while it hovered in front of them so they could toast it to perfection. Now they can do that and make sure it doesn't come out black or burned to a crisp.
What the article fails to mention, of course, is that the device is clearly a miniature torture dungeon where sadists can watch gleefully as their toast browns, blackens and bursts into flames (as illustrated above, or in this clip from Final Destination 3). Now all those kids who delighted in melting toy soldiers in microwaves have a new plaything to help develop their taste for exacting cruel and unusual punishments on captives being held without a fair trial.
