You don't add yet another banking service, you switch from your existing bank to BankSimple. The fact that they're not really a bank but partner with existing institutions is a behind-the-scenes thing that you never come into contact with as a BankSimple customer.

I totally disagree. This is a product for real people not geeks. It's the iPad of banking.

Some people are great at managing their money. Most people are not. A bank that designs its systems to suit an average human rather than to suit the bank itself will be a revolution. This is great design finally being applied to something notoriously difficult for most people.

The big hurdle will be in getting this out of the realm of the geeks and into the general public. If they can do that it will be huge and then every bank will copy them.

I look forward to all banks being simple.
