There have been several reports from interviews from  Intel's CEO Paul Otellini that Intel is planing to enter the mobile chip market again with a mobile version of it's low power Atom chip, code-named Pineview, in late 2009.

The low-cost Atom processor, Mr. Otellini said, is Intel's bid to supply the processing engines that will help vastly expand the reach of the Internet beyond personal computers. He noted "four big new markets for our products" that will total $10 billion over the next few years. The four, he said, were consumer electronics, cellphones, embedded controllers and low-cost computing.
