Not surprised, there is really no need to. Your GPSr doesn't care what time it is in human terms...
I would be more surprised if they acutally didupdate GPS satellites with leap second fixes.
Actually that is one of the jobs of the US Naval Observatory. They constantly update the GPS satelights time and position information.
If you have a hand held gps receiver you have an atomic accuracy clock in your hand.
The USNO mission is to:
2 Provide astronomical and timing data required by the Navy and other components of the Department of Defense for navigation, precise positioning, and command, control, and communications.

If you have one clock you know the time but as soon as you have two clocks time becomes relative.
Resistors, capacitors, inductors, and this new memristor are all passive devices and fundamental parts of all circuits. All materials have intrinsic resistance, capacitive (Electric Field effect), inductive (Magnetic Field effect), and now the theoretic moving of charged dopants. They show up with varying degrees of importance.
Diodes and the other active devices are all a result of using voltage and/or current (as well as charge and magnetic flux) to change mostly the resistive property of a material. In superconductors resistance (and likely this memsistor) is 0 which is far different from not being relevant.
Now at nanometer scales, it appears that this memristor is dominant. As this property is flushed out in the near future, VLSI (Computer chip) circuit design will change. As designers take this new property into account for analysis of current circuits sizes can shrink. As designers start to apply this in novel ways some very cool circuits will be made.
Hope this is helpful. sorry for errors.
