[NuLLKiLL]

I am a advanced user and always always use a TASK killer. Don't kill something stupid and you will not have a problem. I quit using one for about 3 hours and my phones started to ccccrrrrraaaaaawwwwwllllll not fun. I also use Start up auditor and prevent alot of crap from ever opening.

Also on the EVO a program very well can be running. It is true some programs go into a mode where they do not use the CPU or MUCH (still some) memory but that is only if the app was designed well. Many apps are not designed well and will eat memory cpu and your battery.

In the end it's up to each person to use a task killer or not. Many many people use them and have not had any problems. Some have used them and reported it was the reason for all evil on their android device.
