I was really questioning about the SB hinge at the beginning. After I went back to BestBuy and played around with it some more, including pressured test around the hinge while closing. The dawn thing is very rigid and sturdily strong. With that said, I am a little less worry now. Dispike some HW issue I am hearing, I am starting to seriouly considering getting one. As I am pricing up the one I like, say i7/8GB/256GB is $2099 version... then at this price, it put SB to the price range of high end iMac 27" 5k at around the same price(educational price is $2099). Now, I am in delima between the two... Man, this is so hard!!!!!
