You both right. Absolutely. Where I got the impression that using a taskkiller was the right thing to do and everyone was doing.... I don't know. But, your post(s) made me interested in the subject and I began to read up on it. Stopped using a taskiller sometime ago.

Key word is "guessing"

My edge is currently running..

Android Core Apps Background 0.0%
Watchdog Foreground 0.6
Android System Foreground 0.2
Reader Service Background 0.0
etc, etc. All apps listed, listing changes as cpu usage changes,

Taking the 'guesswork' out of anything gives me a warm feeling.

Anyway, responses from the appropriate people are always gratefully received.

My job is done...

Edit: Did not mean to imply any problem with edge.... Never happens.. Just biding my time til Froyo.
