Googles Web-based Chrome OS has always powered Chromebooks, and the operating system may soon see its debut on tablets. If a new report from ZDNet holds true, hardware mainstay Acer could unveil the first Chrome OS tablet at a special event later this month. According to ZDNet, Acers invite for the April 29 event reads a touch more connected, suggesting that Acer has some type of touch-based device up its sleeve for its next reveal.
