Google is currently working on at least two Snapdragon-powered Chromebooks based on a recent Chromium commit. The first was revealed late last year going by the codename 'Cheza' while the new model is known internally as 'Trogdor.' Both are ARM-based Chrome OS platforms that will find their way into OEM devices before the end of the year.
