It's not that it was naive. If you can't reliably foresee what the ratios
will be it would be naive not to over-account for things. Not the other way
around.
The reality is we really do need to get to $150,000ish number IMHO. In fact
ideally it would be a lot higher. Even though it may not prevent things from
moving forward it could slow things down. Remember that 100,000 units is a
small production run in the industry.
Lets not forget a lot of time and money has already been put into this
project. We need to get it to a point where it can stand on its own two feet.
Being reliant on essentially the good will of a single entity isn't going to
achieve the results we need for it to really succeed (by succeed I mean that
it'll be self-sustaining and future devices/cards/etc will follow... we don't
want it to be a one-off device... if it is it's the project will have been a
failure).
This isn't Ubuntu. We don't have Mark Shuttleworth's endless supply of cash
to keep trying. I don't exactly see anybody with a ton of cash in the free
software world that's putting out to fund these types of projects.
