I would probably turn it off because I'm always dozing off on the couch with my phone going any which way. I'm sure some people make good use of it and there's plenty of iOS features that are irrelevant to me as well. But there are probably 100 more attractive things to me for the Galaxy S3 than this so I'm kind of stumped why they'd list 7 relatively different minor gesture ux and yet they fail to include major advantages like homescreen widgets and app integration (intents).
