I have one major thing that holds me back from considering iOS a viable replacement for a more traditional OS for daily computing: App and browser tabs are seemingly (not sure what is actually happening on a technical level) backgrounded if you switch away to a different app/safari tab. This results in the app restarting/browser tab reloading. Perhaps this is some sort of caching behavior, and prior apps/tabs are ejected to make room in memory? Either way, it's very disruptive to have apps/webpages reload when switching back. Until I can count on basic things, like my webpage to still be there if i open my laptop on a plane with no wifi, or my SSH session not to be logged out simply because i switched to a different app, iOS simply cannot serve as my main computing OS.
