Barely two weeks ago, right around Google’s event, ASUS silently announced the Chromebook C423. Now it has done it again, not really announcing the Chromebook C523. The similarity in the name isn’t accidental. The two are, in many ways, identical. Both come in a traditional laptop form factor at a time when Chrome OS tablets seem to be the new trend. The difference is that the Chromebook C523 is larger than the C423. Not by much but enough to be ASUS’ first ever 15-inch Chromebook.
