Question about Spintronics? Anyone?

so........ lots of articles tend to be worded vaguely and it is confusing me.

"Currently, manipulating electron charge is the sole characteristic the electronics industry utilizes in computers and other digital devices."

from my knowledge (hobbyist and first year undergrad EE) no one is manipulating the charge of individual electrons. Charge is dependent on the number of electrons or holes present. Right?

so in saying....

"A major goal in this spintronics research is to reach the precise level of control over electron spin that modern electronics has executed over electron charge."

They mean research is aimed at creating spin potentials (analog of voltage), and spin flow (analog of ampage). Yes or No?

Isn't spin quantafied magnetism? or are the to just related?

then the idea is to manipulate the Norths and Souths of electrons (instead of atoms and molecules)? is this similar to the difference between electrics and electronics?

I know there are alot of question marks up there but I feel they are asking many facets of the same question.

Feel free to refer me to literature or journals on the web (maybe on ieee.org) but i've read alot already and just want a more precise explanation.

thanks
