You’re cooked
The people at British Lion Quality Eggs have developed eggs that let people know when they’re done. The new eggs are sold in three varieties: soft, medium and hard. A special heat-activated logo appears when the egg is cooked to your liking. It even reminds you how it is that you’ve cooked your egg so there are no unpleasant surprises when you crack it open.
Smart idea, STUPID pricing. Eggs are rumored to cost more then $1 each.

I also love the idea, but of course it is overpriced! They should just sell the stickers, so that people could stick those on the eggs themselves.
Wow. Or, you could just learn how to cook an egg to your liking: http://www.cooks.com/rec/view/0,1616,150171-254201,00.html
