Interesting factoid:

"Between them they shifted perhaps 8 billion ARM-based semiconductors in 2011, half of them in mobile phones and mobile computers, the other half embedded in consumer items and elsewhere."

"According to IDC, a research firm, the market for PC-powering chips that use Intel’s x86 processor architecture, which Intel dominates, was about 400m last year."

8 billion ARM chips to 400 million x86. I hadn't realized that the disparity was that big. No wonder Intel is desperate to get some mobile wins.
