 ouch!

 *sigh* yes, a chinese MIPS cpu, whilst wonderfully cheap,
reverse-engineering - i've done it: i have 9 HTC Linux phones and one
ETEN G500+ to prove it - is a complete pain.  i'm not doing it again
:)

 so, this time we play a different game: use the fact that of the 20
people wanting machines _fifteen_ of them are software engineers who
will happily help this factory to improve its value for the world
market by getting debian packages on it, right?

 :)

 that's why adam's going along with his phone, laptop and a webcam and
skype.  we can definitely see from the photo that it has a swirly "G"
and from that we're guessing it's "gOS", converted to chinese.

 okaaay, thaat's what the Ingenic CPUs are, i wondered what those
numbers were.  4720 etc.  ok, they're MIPS processors.  yes.  USB 1.1.
 SDRAM.   366mhz CPU.  wouldn't touch it.  or, more specifically: i'm
looking in a different kind of price-range and a different kind of
feature-set.  between adam and i we must have looked at over 300
systems over the past few months.

 yes!  very nice machine, i know the hardware designer - really quiet guy.

 the touchbook is more expensive so as to give them a good safety
margin.  and the OMAP3530 CPU on its own is $35 even in 1k volumes!
add $20 for 256mb POP memory and you start to see why the price is
$USD 299.

 i've spent absolutely damn months looking for systems like this and
they are juust starting to crawl out the woodwork.
