What features will they take out of IPhone 4S or 5 that will disappoint you? Like in the upgraded model of MacBook pro/air they excluded the backlit keybooard and in the recent MacBook pro upgrade early 2011 the battery life is less (7hrs) then compared to the 2010 MacBook pro (10hrs). Battery life may decrease as using faster processor and bigger screen. What do you guys think! They will have an absolute killer iPhone.
