Sometimes I wonder at how people misunderstand what happens around them. I have on several occasions talked to people who dismiss the iPhone as a relevant device [much like Ballmer dissing the MacAir at mixx08]. I think that one thing is clear about what the iPhone does [very much like the iPod set a new standard for enjoying music on the go] - it sets a new standard for mobile browsing. Once you have seen how it's done on an iPhone you can never go back to a different interface.
What is the natural/smart thing to do? Mimic the iPhone interface on other devices
What is the stupid thing to do/say? The iPhone does not have market share so it does not matter.
LATER EDIT: also because users give this type of reviews of the iPhone
communication is essential to business making and it involves more than the ability to name your product, write a tag line or a press release. It's an intricate, rational and scalable effort and, let's face it, not anyone can do it.
