If the MEMS were 1000 times more sensitive
then that means 2G+/- becomes 0.002G+/-
And I bet that HP being an American company that
does not like competition between companies
( only competition between workers)
will charge X1000 whatever the old ones were :-)
This means only 1/1000 the amateurs will
be able to afford them.

The thing that looks best here is the opportunity
for a very cheap sensor that may be worthwhile in
receiving seismic signals.

I bet this is the thing that may go to MARS.

Maybe NASA helped HP make the thing with its
government supercomputers and physics peoples ???

Will the government get a piece of the action ?

It would be interesting to see more of the R&D
that went into the new device.
