good luck with 2.2!!!! i know some think they are useless or even harmful to your device (for the record, i disagree....but that's a different debate). since i got 2.2 ota, everytime i kill tasks there are AT LEAST 15 running. previously it was anywhere from 4-7. now, i kill all (except what's on my ignore list) and 30 minutes later i kill all and it shows 15 were running. not sure what the deal is or even if it's a big deal, but if you don't want dozens of apps running CONSTANTLY...get your app killer!
