something i've noticed recently is that *applications* these days don't deal well with very slow internet connections or switches between connections. e.g. on safari on iOS, you can type in a web address laboriously using the onscreen keyboard, hit "go" and then, the page tries to load, but never loads because it can't resolve the hostname or whatever as your connection is down. so you hit "refresh" to try to reload the page, and the contents of the URL bar vanish! you have to type it all again!
