To celebrate the August 29 release of our app for Android, this week’s Showdown celebrates the ultimate movie droids. Strictly speaking, an Android is a “human-like robot”, often with synthetic skin, but we know you won’t be able to resist including your favorite droids, robots, cyborgs, replicants and sentient, rogue or disembodied computer voices. So, go crazy, show us the droids we’re looking for.
