Tasker: let's talk about it

Tasker is a magnificent app; I've used it for a while, but then I guess I got tired of it and found that my life was ok even if I uninstalled it.

After reading pretty much every post in the Android Essentials thread, I'm really curious: why is Tasker so essential for you?

Even more importantly, which are your essential profiles -- the ones that make this app a must-have on your phone?
