I restored Mt. Lion this morning and waddaya know? I'm actually getting work done without having to force a shutdown every 90 minutes.

But I'm gonna leave Mavericks on the MBP and use it as a crash dummy when the next couple of updates are released. When I can do heavy lifts on that machine without all these probs, I'll upgrade the Mini even if I have to wait for a .2 or .3 release.
