Both support pen input, and will come with the same S Pen apps found on the Galaxy Note 10.1. (Also known as the ATIV tabs in regions outside the US.) The two 11-inch tablets more or less look alike, except the Series 5 is powered by an Atom-based Clover Trail processor, while the Series 7 packs Core i5 guts. The company just formally announced the Series 5 and it turns out it's going to be joined by the next-gen Series 7 Slate as well. Samsung already showed off its Series 5 Hybrid back at Computex, but what we didn't know was that Sammy had yet another tablet / laptop mash-up in the works.
