New Split Powers is better, but maybe still flawed. Not sure.
The Von Neumann thing doesn't quite seem worth 2 refresh to me. Also curious about how it interacts with the split rebates.
For Ontological Inertia, I suggest you add something like this:
"Occasionally, one of your clones might break free of its link to you and become a character in itself. (This is generally a compel on your High Concept.) A clone that does this cannot be recalled by you and, if you have the Von Neumann's Magic upgrade, can create its own supply of clones."
