Apple's (AAPL) iPad 2 got off to a great start during the first weekend of its launch, selling an estimated 400,000 to 500,000 units. Apple holds a substantial lead in the tablet market over competitors like Research In Motion (RIMM), Motorola Mobility (MMI), Dell (DELL), Samsung and LG Display.

How Much Will Suppliers Benefit from iPad 2 Sales in 2011?

Here we take a look at how much various iPad 2 component suppliers stand to gain from the product's success. We assume that Apple will continue to source iPad 2 components from the same set of suppliers throughout 2011.

Intel (INTC) has a problem. It's the leader in PC chips, but it hasn't done nearly as well in the mobile devices market . To remedy this, it just bought the Wireless Solutions Business of Infineon for $1.4 billion.

Intel said that "The acquisition expands [its] current Wi-Fi and 4G WiMAX offerings to include Infineon's 3G capabilities and supports Intel's plans to accelerate LTE. The acquired technology will be used in Intel® Core processor-based laptops, and myriad of Intel® Atom™ processor-based devices, including smartphones, netbooks, tablets and embedded computers."
