Alternatives to Smart Actions for non-Motorola devices? Motorola's recent selection of Android gadgets (particularly, the Droid Razr) sport a Smart Actions application that automatically modifies your phone settings when certain events occur -- for example, turning off data service and ringer at night, reducing volume when you arrive at work, turn off Bluetooth and Wi-Fi when you get home, etc.

I've seen this in action on my friend's device, and by his account, this is quite a battery-saving and convenience feature.

I wonder if there exists a similar application on the Market for non-Motorola devices.
Well, you have several applications that do what you want. You have Tasker which is paid, Llama which is free and I'm currently using and can recommend, if you look around in the Market, you can find other applications.
