HP has a lot of hybrid laptop tablets and they make the hinges fail much more often.
Only the Surface line, as in where the tablet is the main form with an optional keyboard makes sense here.
That's good to know. I would assume if Apple actually released it they would have ensured the hinge would be as reliable as possible (of course, Hingegate is always a possibility).
I'd also go for an iPad/Surface form factor with detachable keyboard if I had to.
