The device will have a 12.1-inch screen and full-size keyboard, as well as an oversized, clickable touchpad. It will also include world-mode 3G and 802.11 dual-band Wi-Fi. Google promised eight hours of active use and eight days of standby, as well as a webcam.Those hoping to get their hands on a Chrome OS device, however, will either have to wait until mid-2011 or obtain one through one of several Google-backed giveaway options. Google plans to release two, Intel-based Chrome OS notebooks from Acer and Samsung in mid-2011, with Verizon Wireless providing cellular connectivity which comes with 100MB of free data per month for the first two years. According to Sundar Pichai, Google's vice president of product management, CR48 is not and will not be for sale. All Chrome OS devices will be launched and priced by their partners, who will hold their own launch events in the future with more details.
