In Challenge to Microsoft, PC Makers Test Laptops Running Google Software - WSJ.com

"PC makers are testing Google's Android operating system—which has so far been used to power mobile phones—for use in new models of so-called netbooks, inexpensive laptops that have become the fastest-growing segment of the PC industry.

Google, which dominates Internet search, already challenges Microsoft on other fronts, including with its free word-processing and spreadsheet software, neither of which has succeeded in denting Microsoft's Office suite. The effort to move Android to netbooks targets Windows, which generated more than 60% of Microsoft's operating profit in its last fiscal year."
