The quality

When you’re a carpenter making a beautiful chest of drawers, you’re not going to use a piece of plywood on the back, even though it faces the wall and nobody will ever see it.

You’ll know it’s there, so you’re going to use a beautiful piece of wood on the back.

For you to sleep well at night, the aesthetic, the quality, has to be carried all the way through.

---- Steve Jobs (1955 - 2011)

I think that is why Apple win the hearts of the users!
