The only thing boring about the iPhone 5 is the criticism

Developing a fan base is hard, very hard. Apple has that as dozens of websites and spies leaked tidbits of the product so there were virtually no surprises at the launch event. Apple doesn't need to market the product since everyone wants it. And if they changed it too much there would be a bigger backlash than we already have with this dock connector change.
When people complain about how Facebook is always changes things I always argue that it's evolution: things change over time. Usually for the better. The new dock connector is smaller, thinner and probably charges and sends data both faster than the connector that was in use for nearly a decade.
It's boring when Windows didn't do anything new for a long time or when Madden only updated rosters year to year, but that's the great/horrible thing about big companies with lots of customers/fans. Part of the company/fan base wants to push the envelope and part wants to have the same familiar thing with a minor refresh. You always make more profit with a minor refresh so that tends to happen more often.
iPhones are only made to last a few years. I don't think my iPhone has slowed down at all since launch day June over 2 years ago, but I feel like it's time for a new one, with faster internet, bigger display, thinner and lighter. New headphones are cool too!
Fragmentation sucks so anytime a company can get big and continually improve their products and satisfy millions of people, it's a good thing.
