>It was an instant success and was termed the “iPad killer” – much to the dismay of Apple investors.

[Today, Stu Woo and John Letzing for the *Wall Street Journal* reports](http://online.wsj.com/article/SB10001424052970204740904577195371567545142.html):

>The Seattle-based e-commerce giant on Tuesday reported fourth-quarter revenue of $17.43 billion, up 35% from a year earlier. But profit plunged 57% to $177 million as the company continued to spend on warehouses, technology and its Kindle electronic devices. Amazon’s operating expenses rose 38% in the quarter from a year earlier, exceeding its 35% revenue increase.

Sounds like Amazon is really challenging Apple’s top spot…
