If any industry was waiting for a startup to come along and revolutionize it, it's the banking industry.
They know that once you get an upstart with lots of momentum, it could derail the racket they have going on right now.
Good luck to BankSimple... it'll be interesting to see how this turns out. For me, USAA is quite adequate for the time being.
With some help of legislators ;)
Besides which, currency and customer support are two very different pieces of a much larger pie. At best, currency is the "implementation detail" behind a much larger set of day-to-day usability concerns inherent in banking.
Savings, transfers(much faster than any bank transfer, I mean my bitcoin reaches it's destination before I can finish filling in the bank transfer forms), security. All there.
I don't need customer support when there's no problems. I've never had something so easy to use to buy on the internet before.
