This is my big concern regarding the GTA04A45 and the Neo900.
How do we know they will ever have satisfactory power usage.
How do we know if the current issues are a consequence of the hardware design
rather than the software?  We don't!

Until low power usage for a new board can be  positively demonstrated, I
think it would be very irresponsible to make very many of them.

If there was any way that a devel-board could be made so that power feeds can
be cut and an in-line amp meter inserted for each each module individually,
the that seems to me (as a non-hardware guy) like it could be very useful.

I'm still very suspicious of the internal USB driver which is documented as
now allowing the OMAP3 to go to sleep properly....
