I see so many people saying task killers are useless but noone ever really explains why. I can give you two examples from the past 15 minutes where I used a task killer.
1) kicked back to my home screen from Dungeon Hunter but it remained open. Tried switching back into it and was stuck on a black screen. Hit my home button, opened up ATK and killed the process. Loaded it up again and it worked fine. How can this not be considered a valid situation where a task killer helped? I know you can kill tasks withot one but this method is much faster.
2) plenty of times after using my phone for a while it will become very sluggish. Check my available RAM and it's under 30. Hit my atk widget and it rises to 70-90. Phone is immediately faster.
And these are just two right off the top of my head. If I don't do number 2 to free up some RAM I can't score higher than 1300 in quadrant, but after killing apps I can score 1600+.
So please stop saying that task killers are useless, I use mine several times a day. You may not like them, but I don't see anyone getting flamed for not using them lol.
