content: To each his own? Or maybe different devices? I find the uniformity between the apps useful. I don't have to fully learn how to navigate each new app. No hamburger icon? Do I swipe left? Nope. Right? Dunno what that is.. The uniformity makes it simple. And there is a nice variety of customization dev apps put in.  Crunchyroll and whatsapp look 100% different. Yet since they both follow MS guidelines, i immediately know how ro navigate; fitbit is another app which close follows guidelines, yet due to the customizations it looks completely different from crunchyroll and whatsapp, yer once again i immediately understand hoe to navigate. There are also several apps which do not follow the guidelines well at all. I find this frustrating to navigate and often times stop using them. Wasn't that a line apple fans used at one point? It's simple? Very probable I'm confusing groups of people again. Hold back arrow is alt+tab. Extremely simple to switch between open apps returning to their exact state when last used. Back button only jumps out of the application of the screen your own was the /first/ screen when app opened. Well, what's back from before opening the app? The home screen of course! This can be confusing if you clicked a link from one app which took you to a screen within another app. Once again, hold the back arroe and you get alt+tab functionality. If you're not doing this, you'll have a frustrating tine. And it's not true to say developers are locked into that design. I do have several apps that look exactly or close to their android counterparts. Just my thoughts and wanted to share a bit of info about that back. Once you learn the two things about it, it's extremely efficient.
