Tasker sounds like a really neat tool... I guess it is a question of just how much I get into my phone. In one possible future, I'll be moving to Boston in the fall and taking some time off, at which point I'd be buying a new laptop, learning R, and otherwise trying to improve my computer & life-hacking abilities, so I could see tinkering with Android flexibility fitting in well there. But... if I don't move to Boston, I'd probably poke at Tasker the way I poked at Papers as a way of keeping all the scientific literature I read organized... which would push me towards the cleaner iOs.

Also, you didn't mention that the Android supports Facebook Home! (ok, that might be a minus, not a plus...)
