I've never had a subpar user experience with Apple. I think chances of anything other than a tiny quirk being wrong with 6+ usability is quite low. Unless you're referring to the size, in which case I'd just go to Best Buy and try some large phones out.
Yeah i was referring to the size, i dont live in the USA so i will probarly have to wait some time to see it in person im afraid. Im really liking the idea of a big phone, but not being able to use it properly with one hand is something that *may* bother me.
