Mate remember one thing. The more free RAM you have on Android, the slower the device is. In Android OS it's all about using RAM memory. Why? Imagine you open e-mail app. There is link to open some link so you open browser. You found some document on the website and you want to download it using file manager and the open it using text editor. As long as your applications are kept in the memory, after pressing "back' button you will be immediately in previous place. But if you will decide to make killing the processes in the background more aggressive then every app after pressing "back" button will have to be re-opened again - taking resources, battery, cpu and
time.
I hope that explains why task killers are bad on android and a lot of free RAM memory is wasted memory
I agree with you, the more you use memory, the more multitasking is good.
BUT I just wanted to say that if you have more free memory, the launched app is smoother, that is a fact.
Ok you will have to launch it again if it has been killed and you will loose some battery, but, for sure the launch won't be too long thanks to the high free memory and the application will be smoother than if there was several apps already in memory.
For transformer, we have 1 gigabyte so you are really right here.
No need to sacrifice multitasking because there is enough free memory to have things smooth in almost every situation (even though when I launch a benchmark or a game, I prefer killing no needed tasks to have it more performing).
But for 512 mb devices or less, I prefer sacrificing a little multitasking to have smoother device (and loose some more battery too but I don't care if my device is smooth)
Hope you will agree on that, just wanted to add some more information on your good arguments because I think noob android users are using task killers because of what I am talking about here and I saw everywhere on xda that experienced users like you always say that without understanding that with more free memory the device is indeed smoother (but I repeat, less true in the case of the transformer).
