All Chromebook Plus laptops offer faster processors and double the memory and storage, giving you the power to get more done, easily. All Chromebook Plus laptops also come with a Full HD IPS display — which means you get a full 1080p HD experience when watching streaming content, and crisp, clear viewing for reading, creating content or editing photos and videos. Finally, there’s a 1080p+ webcam with temporal noise reduction for smoother, more lifelike video calls.
So basically, because the Chromebook market is dominated by cheap crap, Google has had to create a new category of Chromebooks that are slightly less crap, so that buyers who don’t want crap but instead want slightly less crap can distinguish the slightly less crap from the crap so they end up buying the crap they want.
Like gaming Chromebooks, I give this like two years before Google sees something shiny and this whole Chromebook Plus thing is dead and gone.
