An iPhone is usually a well balanced phone. It may not have the best of anything, but is usually right there at the top. And if you want a great camera so badly that you are willing to compromise on everything else, by all means, buy a dedicated digital camera. Similarly, if you want your phone to be so good at playing music that you are fine with the other compromises, you might want to look into a dedicated music player. Smartphones are meant to to generally purpose jack-of-all-trades sort of devices and the iPhone excels at that. If I want a device specialised for a purpose, I’ll buy the just that — not a smartphone.
