People always down vote when I point that out as well lol. Windows mobile was already moving towards icon based UIs pre iPhone, so while the UI was a definite improvement it wasn’t the revolution it’s made out to be. The iPhone 1 had no app store or 3g so was not good for emails and, back in 2007 when flash still mattered, couldn’t access most of the Internet where windows phone could. I’m pretty sure it was successful purely based on the iPods popularity, at least until the iPhone 3gs and app store came out and the iPhone became arguably a better smartphone than those that came before.
