It feels like Apple has taken a step backwards with iOS 10.1, offering an iOS6-esuqe update style (aka, adding nothing). So far, it's looking like the ONLY thing that 10.1 is adding the the portrait mode that we already knew about. Nothing else. That's very disappointing, especially for non-7 Plus owners (which when you factor in the amount of iOS 10 devices, is a very large amount). Apple has previous done some very great stuff with their .X updates. The entire lifespan of iOS 9 showed that they were dedicated to continuing to add new features and functionality with every .X update. This is seen best with 9.1 with 150+ new emoji, and 9.3, which added Password notes, Night Shift, and a load of education features. iOS 7.1 updated the UX design. 4.2-3 and 8.1 added nice small visual changes, and some small feature additions. 3.1 and 5.1 changed the system in noticeable ways (in terms of functionality), and heck 8.2 and 8.4 added an entire new SERVICE and new apps. The fact that 10.1 adds literally nothing to non 7+ owners makes it feel more like it should be iOS 10.0.2, and a build that's only for the 7+, not a whole version upgrade. TL;DR: Apple has historically used the .X upgrades to introduce multiple new features and system changes that can apply to all devices, not one feature that only one device benefits from.
