The faux stitched leather look has become something of a Samsung tradermark but only for its more premium or pro-focused devices. It is present in the Note 3 as well as the Galaxy NotePRO and TabPRO tablet line and various accessories that have come out including Ethernet dongles and battery accessories. @evleaks has revealed what looks to be an upcoming Chromebook that sports the stitched leather effect, it's been a while since Samsung's released a Chromebook so this could be something Google is readying for release sometime soon.
