"it'll take years"
No, at this point it will take decades.
Spintronics ? Purely lab-based. I'm impressed that they've found another way to store digital information. I'm happy that an EM blast cannot erase it. I am however too old to be taken in by the hype.
Maybe, just maybe, a copper-whatever-arsenide SDD thingy will be commercially available before I die.
I won't hold my breath. Not until I start seeing those wonderful nano-carbon-tube batteries I've already been promised a decade ago.
