The XYZ crew got a look at the picoPSU at CES, & they were impressed. The thing is damn tiny, that's for sure...

"Many companies wait for CES to unveil their new toys but also with all those companies displaying items it is impossible not to see things which you have not seen before. For me, one such item was the picoPSU, what turned out to be the smallest 12V snap-in ATX DC-to-DC power supply ever."
