Just like Mac books, the iPhone will have a small market share but will be very profitable for Apple.
Apple's ideas may look obvious and their decisions my look easy to decide after the fact, however, the same can be said for a winning chess move after its made. This is an easy fallacy to make.
"If I have seen a little further it is by standing on the shoulders of Giants." - Isaac Newton
While many believe that was the sentiment being expressed by Newton in his letter to Hooke, some researchers have suggested that he was actually using the phrase "on the shoulders of giants" as a veiled insult of Robert Hooke, who was a rather short man. Newton had a reputation as somewhat of a petty and vindictive man whose ego clashed with those of his rivals in the scientific and mathematical communities. One of these rivals was Robert Hooke, who had been involved in a long-running fued with Newton over which one had discovered the inverse square law. Although Newton's letter to Hooke appeared courteous on the surface, some historians have concluded that he cleverly employed the phrase "on the shoulders of giants" to ridicule Hooke's lack of physical stature and imply that he lacked intellectual stature as well.

There's been a bunch that have been in the 200-300 range but apparently they don't count as 300 is the magic number (assuming you are holding your phone a specific, yet unspecified, distance from your face).
A feature which won't be included in Windows Phone Series 7, and a feature which frankly sucks on my Android phone.

A 100,000:1 contrast ratio doesn't do you any good when you can't even see anything in sunlight. OLED may give a great contrast ratio, but any direct light (ex: being outside during the day, a common usage senario) means that you can't see anything anyways.
