 not necessarily, but $150 times 15 equals $2250 - we juuust cover the
costs if there is only one revision (unlikely).  $150 times 20 equals
$3000, we'll be able to cover some more revisions for that.

 basically we'll do one and one only at a time, first of all, and
experiment in 1s or 2s.

 we'll just have to see.

 surprisingly: 4 excluding me and you.   $150, $150, $180 (and one
wavering/conditional $100).

 yes, that's one option - _if_ we get it right first time (unlikely,
but always a possibility)  basically, if we get it right first time,
then... well, it would be _nice_ for me to get some of the $3,000 back
early :)

 yep.

 i want the first batch to be 1gb, option of 512mb.  it's an extra $5
or so - it reaallly isn't going to break the bank.  1gb RAM, 1gb NAND,
1ghz S5PC100 james says he can do for $43, quantity 20.  and that's
slightly more money because he has to hand-solder them :)

 yep.

 yep.

 it's faster, and it's also future-proofing: for mass-production, NAND
is cheaper than a micro-sd slot.  $0.50 less will make all the
difference.  so, thinking ahead, if you're going to do the work, throw
it in...

 yep.  serial port, JTAG etc.

 longer, no - wider, mayyyyybe.  it's about 3-4 mm that isn't being
used, but we really need one of the Si-Chang 7in MIDs to double-check.
 to be on safe side, it's probably best to stick to 35mm ( by 67mm ).

 i am not anticipating / i would be incredibly surprised if there is
any difference.
