Microsoft is going to war with Googles Chromebooks. The Windows OS maker has announced that it is working with its hardware partners to ship low-cost Windows 8 laptops in time for the holidays that will take on Googles Chrome-powered systems. The Windows-based laptops, which will come from the likes of Acer, HP and Toshiba, will reportedly sell for between $199 and $250, with smaller models going for as little as $99.
