Updated from 10:34 a.m. EDT with stock informationGoogle ( GOOG) is targeting another market where Microsoft ( MSFT) has dropped the ball. Setting its sights on the fast-growing netbook segment, Google expects to have a Chrome operating system ready for use a year from now. Google's lighter, faster, and presumably free Linux-based system will attempt to power an array of devices in between mobile phones and notebooks. Google's Android software has already been sweeping Microsoft Windows Mobile out of the smartphone picture. But Android isn't up to the netbook task, and Microsoft's Windows systems are too large and too expensive.
