The magic of Steve Jobs may be absent in his successor Tim Cook but Cook's leadership is working well in Apple. On Tuesday, the tech giant has announced that its net profit has more than doubled to $13.06 billion in the fiscal first quarter. The Holiday sale of 37 million units of iPhone and 15.4 million units of iPad sale were seen as the biggest contribution towards the outstanding profit in the holiday quarter. No wonder, iPhone and iPad account for 72% of Apple's total revenue.

Total revenue was unveiled as $46.3 billion with 73% sales growth from a year ago, exceeding the Wall street analysts estimate of $38.9 billion, according to Reuters. After the release of its result, the company shares rose up to $33.03 or 7.9% to $453.53 during extended trading hours.

We're thrilled with our outstanding results and record-breaking sales of iPhones, iPads and Macs, Cook said in a statement. Apple's momentum is incredibly strong, and we have some amazing new products in the pipeline.

With rumors growing about the next generation iPhone and iPad, Apple seems to have kicked off year 2012 on a high note under the spirited leadership of Tim Cook.
