No mention of how fast these transistors are
Odds on bet slooooow.
The problem with this tech has always been if you use the really low cost methods you end up with really slow transistors. IIRC the record is something like 20Mhz.
OK so that's a pretty sporty PC, back in the mid to late 80's.
Now how do you do WiFi, BlueTooth etc with those sorts of frequency?
