Microsoft is aiming straight for Google’s Chromebooks this holiday season. At the company’s partner conference today, Microsoft COO Kevin Turner revealed that HP is planning to release a $199 laptop running Windows for the holidays. Turner didn’t provide specifications for HP’s “Stream” device, but he did detail $249 laptop options from Acer and Toshiba. Acer’s low-cost laptop will ship with a 15.6-inch screen and a 2.16GHz Intel Celeron processor, and Toshiba’s includes a 11.6-inch display. It appears that Intel’s Celeron chips will help Microsoft’s PC partners push out cheaper devices in the race to the bottom. Turner also revealed that HP is planning to release 7- and 8-inch versions of its new “Stream” PCs for $99 this holiday season, both running versions of Windows.
