It's a matter of personal opinion - not everyone has to like (or indeed hate) the same things that you do. Just because you don't like something doesn't make anyone who does an idiot. Assuming that anyone who disagrees with you has an inferior mind however, does make you the sort of person that I'm probably glad I don't know.

Personally I buy my phones to use as phones (funnily enough - although I text a lot more than make calls), but no matter what great functionality a "smart-phone" might have I still get bored of it after a few weeks - I'm fickle like that. One other thing the iPhone does better than other phones (or rather Apple have done better than other manufacturers) is the provision of extra apps, games and utilities to supplement the user experience. Bollocks to the stupid stuff like beer glasses and fart apps, but there is still a whole host of actually useful apps and some pretty decent games (Wolf3D anyone?)

As for the interface, in your opinion it may be shit but I think the majority of people (iPhone owners or not) would agree that it's one of the things Apple got very right.

The fact is, if you want a PHONE purely for it's phone functionality I wouldn't touch any smartphone with a bargepole. None of them can hold a candle to a simple basic Nokia for speed and usability in that area. If however you want a phone which will integrate with pretty much any other part of your life, then there are a few decent choices on the market now and you simply choose the one which is right for you.
