Can anyone provide a list of the major differences? I've been trying to sort it out from reading the product pages at E-on, but I'm not sure if I'm missing anything. So far, I'm assuming that:

Infinite will have EcoSystems II, and PS won't
Infinite has some animation features (graph editor, wind generators) that PS lacks
Infinite has a "purge memory" function and PS doesn't (?)

And... is that it?
