Smallest ever transisters= tiny PC's

It looks like those clever science bods have done it again and gone and invented transisters that are 1molecue long.

Together, the two studies could bring the final frontier in nanocomputing -- a single-molecule transistor -- considerably closer to reality.
So we go from:

to one molecule!! So a PC the size of a postage stamp??

(Due to the quantum wavelike laws of nature that electrons follow, attaching electrical leads at the 12 o'clock and 6 o'clock positions causes the current to cancel itself out.)
OK, too much physics for me there, but basically its really small!!

Full article at Wired and a nice summary at Bit-Tech

As much as i love the idea of small computers, i still want a big a$$ rig sitting on my desk growling at me
