I can flatly say I don't believe you. When you are not using an application out right, Android will sleep the process. The only thing that will keep running is background services. Killing the applications like you are doing is only making the services restart ad-nauseum. Read some of the excellent information on the boards, and if you are still feeling froggy (which you should after reading the information) root your phone, and upgrade to 2.2. The upgrade to 2.2 made me about as happy as I could ever be with my Droid. I did it on the first day I had it.
everyone has their own opinions on taskillers. some apps are poorly designed and NEED to be closed when done using it to avoid it killing the battery. but hey do what u want..
I see what you are saying, however I have seen zero evidence that killing tasks is in anyway beneficial to the performance of the device. The proper way to deal with this is to not install poorly designed applications that constantly (and erroneously, as far as I am concerned) chew on processor cycles in the background. Any real mobile application developer does not do this at all, and I have had no reason to ever kill a task that wasn't malfunctioning out right.
Also, I suspect a lot of people have performance issues after loading up their homescreens full of redundant and wasteful "monitoring" widgets that are constantly polling resources and not only impacting device performance, but yielding terrible battery life in the process
