Google have been pushing their Chromebooks pretty hard lately. With options of any shape and size available from multiple laptop manufacturers including Samsung. However, it looks like Google will soon be taking matters into their own hands (think CR-48) and releasing their own device rumored to be the Google Chromebook Pixel. There's a neat video and some pictures that have leaked sharing all types of information.
Acer Iconia Tab A700 is about the closest an Android tablet has gotten, until now.
