Dieter Rams' 'Ten Priniples' of Good Design

I went to Dieter Rams' exhibition at Design Museum in London, and it was really impressive, so I quote his principles:

1 Good design is innovative
2 Good design makes a product useful
3 Good design is aesthetic
4 Good design helps us to understand a product
5 Good design is uobtrusive
6 Good design is honest
7 Good design is durable
8 Good design is consequent to the last detail
9 Good design is concerned with the environment
10 Good deisgn is as little design as possible.
