Wadstrom on the spot with ONE
Nicolai Wadstrom is a hot Swedish blogger I do recommend you to read his post: With fans like this, you do not need a design department:
Apple’s design department get ideas and design concepts from their fan and customer group. Have you ever Sony-Ericsson, Nokia, or Microsoft getting this type of mockups of potential products for them to produce “designed” by their customers? Wadstrom.net
Love hes point: Stefan Engeseth is right on the spot here with his book “One”.
