So I'm attending engineering school and I need a computer for inking. Its between the Lenovo yoga 12in 2nd gen. and the Lifebook T935. But Lenovo has info on the hinge testing on their website, like over 2000 times a day, crazy. But Fujitsu doesn't. What are your experiences with the hinge or hinges on the T904 or T935? not the T902. How long have you had it? Thanks to all who reply!
