Another big win in my books, straight out the gate, is it runs on Linux.
I know Linux fanboys like to crow about how Linux performs so much better, but I am not a Linux fanboy - I don't really like the OS. But I have tried it out with Houdini, and it absolutely flies compared to Windows. It feels like I upgraded my system hardware, when all I have done is reboot into a different OS.
Adobe, and Ae specifically, was the one thing that was keeping me from moving my work to Linux entirely, but with Autograph I can potentially finally do that.
