I'm an iPhone lover and apple hater
I don't think it;s a case of people thinking it is the best purely on a teh basis, but it has consistantly been the best package. The user interface has always, and still is better than most, and the materials have always had a more premium feel to them. I think the iphone is still one of the few non plastic smartphones on the market? I personally love my 3G and will more than likely get a 4 once they sort issues out. I have tried, in vain, to find another phone that pleases me as much. Andriod phones are very good phones and the tech will surpass the iphone on some levels, but they just don't look or feel as good as an iPhone - simple really.
