I think, practically, everyone will need at least a cheap-ish android or iphone, perhaps $300 (and a new one every few years ...), to be their locked-down "agent" for using financial or government services. It's not for you, it's for the government/banks, it is their agent for talking to you.
Kinda weird, if you think about it. But that seems to be the way it's heading.
