Yes I'm curious too.
I believe the "Secure Element" in iOS and other smartphone payment systems with the EMV wireless payment standard, all use this as their OS/ecosystem, as it's mandated by the payment industry. So it is widely used.

In terms of use, there's an additional complexity for using JavaCards. We try to solve that a) making the code easier to port and b) providing access to smartcards via TCP/IP where it makes sense to have them in a rack.
In general, they don't run out of battery and you can print your headshot and name on them.
In terms of "hardware" - all chip debit/credit cards use the same processors (actually they are a complete computers with EEPROM, RAM, co-processors).
