I find it to be quite a stunning design. The curved glass on the back makes far more sense to me than on the front display and I never preferred a removable battery--would much rather have a nice, sturdy unibody build. The prevalence of fast charging and wireless charging makes it even less of an issue, IMO. I'd gladly take expandable memory via a slot on the frame but I've never been one that needed enormous amounts of storage so these internal storage amounts suit me just fine.
My biggest issues with Samsung have been two-fold. First, I find the user experience not enjoyable in the slightest. And second, Samsung doesn't offer carrier free, unlocked devices. Until the latter changes, at a minimum, I won't even consider another Samsung phone.
