What's so bad about that?
No, you don't. Just because an app shows up in a process list doesn't mean it's consuming resources. (Other than memory, and background processes are automatically killed as needed to free up RAM).
Hopefully this isn't going to allow apps to just run any random equivalent of a tight loop of their own (memory chewing CPU and battery consuming) design.
I'd also like a reverse chronology notification history that pops up from tapping on the click.
To even call it multi-tasking is a joke.
The reason is that intermediate users who know just enough to be dangerous think that they're necessary, when they aren't: http://droidtalk.net/should-i-install-a-task-managerkiller-o...
"Is it really necessary to be notified about every new tweet or status update? Reduce the refresh times on your social networking applications and reduce the number of items you’re notified about. Reduce the number of widgets you have on your home-screen, instead replace them with program shortcuts, you’ll still have quick access to your most used programs without the constant battery drain caused by continuous data pull."
