When i first got my hero i was told to install a taskiller. I found this annoying and bothersome and my phone had several issues such as force closing and awake time. Then i read somewhere online that Android "is a smart os" and you don't need a task killer. So I uninstalled. Everything got better. My phone will lag or slow down here and there, but i think that's more the insufficient hardware of the hero... Usually I just wait a second and it's fine. Or press the home key. But here's the thing. I bought my wife an Intercept, and two best buy mobile employees told me to install a task killer - that this is how you "manage" android. Honestly, if this were true... Which I don't believe it is... I would not like the Android OS. But then a Sprint employee told me to also install a task killer... Only HTC has confirmed my earlier understanding that they're not necessary. So I've heard mixed things. In my own limited experience, it's not necessary. But i still see articles and forum posts talking about using them. So what is it? Are task killers a nagging and persistent myth... Or is there any real net benefit from using them? Or is it that they were more useful to version 1.5?
