Why Apple likes ARM

Apple is sitting on a heap of cash – more than $40 billion at last count – and the big question has been what the company will do with it. Investors in London this week are buzzing about one possibility: It might buy ARM.

ARM (ARMH) shares have shot up this week on the speculation, bringing them to levels they haven't seen since 2002. As of now, it looks like it MORE

Intel's latest headache: Nvidia

The chip giant settled with AMD. But another rival is making noise about anticompetitive behavior.

You'd think Nvidia CEO Jen-Hsun Huang would be happy.

After bumping along as low as $7 a share at the beginning of the year his stock is up near $14. Several months ago Apple (AAPL) began using his graphics chipset – a group of circuits designed to work together – across nearly its entire line of Macs, MORE

California: Too Big Not to Fail?

The state of the state? "A train wreck," says one official.

If the world's eighth-largest economy were a member of the proper religious order, it'd be time to call in a priest to administer last rites.

Name almost any serious malady and the state of California has it: the nation's highest marginal tax rate coupled with an abysmal public education system; the most home foreclosures; a free-falling commercial real estate sector; lame-duck MORE

Hardware nerds are hot

Changes in computing mean software companies need hardware-savvy employees

By Sam Blackman, CEO and co-founder, Elemental Technologies

Whether we knew it or not, we've all been relying on something called "Moore's Law."  Back in the 1960s, Intel (INTC)  co-founder Gordon Moore noticed that the number of transistors that could cheaply be placed on an integrated circuit had been doubling every two years.

There's going to be a PC retail showdown this holiday season. Let's call it the netbook vs. the nymph.

In the netbook corner: the cheap, small, underpowered laptops that are all the rage lately. Asian manufacturers like Asus first introduced them, and consumers love them because they handle documents, e-mail, and web surfing for as little as $300. The big PC makers offer their own models, but also secretly hate that MORE

Based on Intel's dramatic sales warning Wednesday, you might expect rival Advanced Micro Devices to just crawl into a hole and die. If the economic mess is tripping up the most powerful chip company on the planet, how could its underdog challenger stand a chance?

Indeed, investors MORE

Intel's dire warning

In a surprise announcement, Intel (INTC) said Wednesday that its gloomy fourth quarter forecast wasn't nearly gloomy enough. Instead of pulling in between $10.1 billion and $10.9 billion in sales, the chip giant expects closer to a dreadful $9 billion. The stock tumbled more than 7 percent after hours.

It's hard to articulate just how bad this news is.
