I don't really care for updates sicne iOS 7 soured my view of them. Also, if you never update anything your device cannot ever slow down. The Note Pro actually was trying to compete with the then new iPad Pro. TouchWiz was to me very nice looking since it incorporated nature into it, and I'm a huge nature lover, and very outdoorsey. It fit me well. Today, that UI is just a background wallpaper of a lake or forest and replacing the default stock Android sounds with Samsung ones via Zedge. My Moto G Stylus has all the Samsung sounds, including the SMS tone and forest alarm. Other than that, and running an iOS'y launcher and lockscreen, it's pretty much left alone. I don't need TouchWiz's deep integration anymore, but I do miss it a bit. Especially the droplet touch sound.
I'd pay tons of $$$ for a device that never got updates unless I specifically chose to, and never nagged me about it, or worse, forced them on me. After iOS 7, I no longer believe in updates. I might choose to every now and then for apps, but I always read the changelogs, being cautious about any that mention 'redesigned' or 'reimagined'. Also make sure I can undo them if I despise the changes. It doesn't take much to annoy me, since I get used to interacting with apps and can often use them blind (most of the ones I use are from 2009-10) and just simply repositioning the settings icon bugs the living heck out of me. Just let me do as I please and enjoy my device, OEMs!
