I would add, that you need to draw a line in the sand between the 'consumer' (don't flame me, I am just struggling to find a better term) boards and those that are positioned for production/enterprise.
One way to draw the line is whether the board is delivered to be used as-is, vs. with the expectation of further development activities that will change the work product that shipped with the board.
In the first case, all you care is that it works when it leaves the dock. In the latter case, you care more that it can't be easily broken later.
That's a pretty big difference in my experience.
