Task killers haven't been popular or recommended since the release of Eclair and really Froyo (ironically most simply destroy performance these days, but people aren't bothered to learn about Acitivity hibernation in Android so they don't release they're shooting themselves in the foot needlessly flushing ram and then reloading the app from a closed state when Android seemlessly suspends them). 90% of the time that apps are draining the battery, it's because of a user-initiated wakelock. There are very few if any apps that just "drain the battery" these days. As for multitasking, it's been around for a long time sure, but there are various implementation details that are in common among Android and iOS (but not Mango or webOS necessarily). I have no desire to point fingers of "theft" or "copying" but inspiration doesn't seem unthinkable.
