Here is my (Warhawk7) Android Mindblade Magus.
Flavor-wise, she has learned to use her nanites to cast spells and manifest a weapon for self defense. Basically she uses her mind and exerts her will over her nanites to do what she wants.
Mechanics-wise, nothing changes. She still casts psychic spells and manifests a psychic blade as per the archetype. I just thought that a psychic android would be able to control the nanites in her body, which is why I went this route.
I was thinking of getting her the Third Eye feat at some point. Makes for an interesting added sense for her.
