There's a thread similar to this on one of the Hero forums. I tried to stop using the task managers on the hero, but I noticed a quite a bit of lag once stuff kept building up. On the Moment, I was running into several issues with apps, and I figured it was due to the task manager (i use advance task manager). So to test my theory I stopped using the task manager and the device works as it should. What i found was that even with a lot of usage, this device does not slow down. Not sure if it's the lack of the sense ui (i'm using open home), the fast processor, both or what....but this phone can handle everything I'm throwing at it.
My advice, stop using whatever task killer you're using. One less thing to worry about makes for a better phone experience.
