yes!  you wouldn't believe the cost i've found (10k volumes).  a company in
HK, recommended off of ST's web site, they are doing such high volumes that
even the 100-pin STM32F106RVT6 is just under $2.50.  stunning.  they sell
in lots of i think it's 850, they come in packs, they just ship them
straight out, no splitting packs, nothing.

it's... mad.  absolutely mad.  _so_ no need for any of these 8052-based
ICs, one for camera, one for audio, one for this, one for that.  i had
absolutely no idea that there were so many processors in a single tablet.
adding it up, there must be what... *eight* separate processors, even as
many as 10 or 11 if it's got 3G and GPS.
