According to The Wall Street Journal, Apple is no longer seen as the coolest player in the hi-tech market. Although they were unable or unwilling to name a successor, the WSJ believes that Apples falling share price is indicative of the fact that no new products are coming out of Cupertino.
Apparently the iPhone 5, iPad 3, new MBPs and rumors of an iPad mini are (yawn) more of the same, and Apple has lost the competitive edge.
For some reason, I can't link directly to the video on the WSJ website. If you want to take a look, it's the one asking the question "Has Apple lost it?"
