It's a Linux live system (with permanent storage on a USB stick) geared specifically towards online banking.
I believe that quite a few people actually use it.
Of course the hardware is the same, but you get a clean single purpose software system.

That sounds like a great attack vector. How secure are factories where discs are pressed? Even without access to the factory you could buy a bunch of magazines and repackage them with compromised CDs.
Repackaging it seems to be tricky, since the paper inlay is bound in the magazine, it's not just stuck on the cover or whatever. You tear it out at a perforation, leaving part of the DVD cover inside.
There are much more exposed attack vectors on online banking users, I would think.
And you can always just download the ISO and check it against the hash (and the PGP key).
