This is so good I couldn’t NOT post it.
The WP7S layout and typography have a looseness found in posters, commercial art and marketing, an inappropriate metaphor for a handheld information and communication device. In the splashy panoramas, there are hints of design-by-focus-group (which is like hiring temps as your design consultants). Instead of impressing focus groups, designers should do a thought experiment: Imagine what Steve Jobs and Jonathan Ive would have to say about your interface. As Jonathan Ive said: At Apple “we don’t do focus groups.”
That is just the opening paragraph.
