I'd say the difficulty now is how online services are integrated as part of being able to function in many tasks we're now asking phones (or mobile computers) to do. If you're only doing local stuff then you can probably get by, but so much of the world prioritizes online and having secure payments if your phone doesn't respond correctly to those services then there's a risk of exclusion or a time/money cost to use them in a less convenient way.
