Samsung is a TOTALLY different case. They don't compete with Apple by making ARM SoCs, they compete with Apple by selling smartphones.
The article is merely suggesting that Intel make ARM SoCs for Apple, while selling x86 SoCs to Apple's competitors. No one is suggesting Intel should start selling smartphones.
Intel already have the capabilities in designing their chips for FPGA usage which diversifies their functions in a chip. I had rumours on a Cedarview Development Board with FPGA capabilities. Also, not to mention the embedded automotive market that they are so dearly focusing on, especially the IVI projects they have been doing for a few companies for the past few years. However, as for mobile phone and tablet market, they might not have a strong foothold with Qualcomm, Samsung and Nvidia app processors flooding the market.
Otellini's leaving because he's a wise man. Tough economic times, even tougher semiconductor market, competition becoming thornier than ever, he knows the semiconductor industry has some major contraction ahead. He doesn't want his legacy tarnished by something he doesn't have control over.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
