If you want to run the full version on embedded, there are lots of SSD's
these days with wear-leveling subsystems to address the "write endurance"
issue of nand flash memory. Some SSD's (such as Intel's newest SSD family)
even take it a step further by adding extra blocks to swap out when a block
becomes exhausted. Intel's version apparently also does something like
S.M.A.R.T., but instead of monitoring the length and growth rate of the
master defect table, the SSD equivalent of SMART instead monitors the pool
of spares and can inform the OS when a disk failure is in approaching. Many
of us have hard-won experience indicating that SMART is pretty crappy
(because growth characteristics of the master defect table are in fact only
loosely correlated with actual disk failure), but I suspect that the SSD
equivalent will provide a reliable prediction.
I tend to think we're at the dawn of a new era in storage. With SSD's &
low-power fanless ITX systems, it seems like the line between 'full' and
'embedded' is becoming a bit fuzzy.
We're going to build up just such a system in just a few months after we
close a couple of open projects. Has anyone done this already, & have
experience to share?

If you have a full system, just run the full release.
I know the embedded version tries to write as little as possible on
the drive in order to increase the longevity of CF cards etc.
Does the full version do this?
No, it's not relevant on hard drives.
In other words, *don't* run the full version on embedded hardware :-)
Some people do, I know of systems running full installs on CF for
years with no trouble (I also know of people killing the CF in a
matter of months). If you care about the life of your CF, yeah I
wouldn't recommend it. I would never do it on a critical system.
