no there is NOT an "announcement for $15 BOM", there is a *RELAYING OF
INFORMATION FROM THE CPU MANUFACTURER WHO SAID THAT IF YOU MAKE A 7IN
TABLET **THEY** ESTIMATE THAT THE BOM OF THAT 7IN TABLET'S PCB will be
around a $15 BOM.*

i wish people would actually listen to what's being said.  sorry tsvetan.

ellen's team is going through the approximate BOM (with the major
components) at the moment, so we will have a better approximation soon
enough, and once bari's finalised the schematics, we can get an exact quote.

there are two plans:

1)  rhombus tech will for smaller quantities (under 10k) add varying profit
margins - probably something like 40% (TBD) minimum, increasing to 60%
(TBD) for the very-small volumes - this to cover costs, warranty etc. and
also provide a stable financial base to develop future products.

*however* as this is a CIC, there are two extra things:

a) if anyone would like to pay *more* than that, we are quite happy for
them to do so.
b) if anyone wishes to pay *less* than that, there will be a sponsorship
programme which the "admins" (phil, wookey, james, alain etc.) will
formally approve once the individual's proposal is in.  however, this
programme can only be activated if there is actually any profit available.

2) quantities of 10,000 and above will be referred directly to the factory.

yep.  precisely.

see above which is *NOT* yet finalised, because we have to discuss with the
factory.

in that (private) email i sent to you, there was no actual link made
between "$7" and "500,000".

yes there is a reason for that.

that's what we've done.  we received the EVK schematics from wits-tech.
 the EOMA-68 CPU card is actually a cut-down version of the EVK schematics.
 we picked the A10 not just because of the low projected price but also
because its interfaces are near-direct match for EOMA-68.

the other one that we looked at closely was the AML 8726-M but they messed
us around with GPL violations.
