You are [unfortunately] quite right.  The (relative) success smart cards have
had in controlled environment such as payment terminals cannot be translated
to the completely uncontrolled consumer computer base.

I see two possibilities:
1. The easy one.  Let Apple with iPhone/iPad provide us with the "container".
2. Define a new container where the interface is strict and support provisioning
so that even Joe Sixpack can succeed.  This is my take on the subject which
though is about 100 times more difficult than what Apple needs to do so
I guess I'm an idiot even trying...

I just don't like the idea of going from an OS monopoly to a fullblown
OS + Device + Infrastructure monopoly. Banks and Governments have little
to compete with and will also [much too] late realize they're screwed.
