[Freedombox-discuss] Processors without visual serial numbers exist

[Tim Schmidt]

You realize that, with or without a PSN, your hardware will contain
unique IDs like it's network card's MAC address, hard drive serial
numbers, etc.  And that the unique configuration of hardware which
comprises your computer - all of the UUIDs combined with firmware
versions, screen resolution, disk sizes, the number and type of
devices which are connected, and even which wireless access points are
visible - can be combined to make for a VERY strong globally unique
identifier.

Of course, should you chose to run software that respects your
privacy, absolutely none of that matters.
