oh, well I haven't seen a prebuilt erase itself in a long time, we've been making tweaks to keep that from happening (i.e. no bootloader, no self programming at all, bigger caps, rearranging the power circuits to keep the brain alive longer, etc. But of course that doesn't mean it won't ever happen to the prebuilt. I have done things like connect the mpguino power through a big file and drag the conductors along it (insanely erratic power), and it still had the right programming. But solid power is still probably good thing.

My arduino based version forgot its programming several times when the power was flakey, but this isn't conclusive, but reason enough for me to not retain arduino-ness.
