Hey, I'm a member too.

I use multitasking to keep track of what I'm currently doing. Sometimes I open apps or browser windows to new windows even though I do not go to them right away. They're there to remind me to read them later. Especially on a mobile device the use is very sporadic. When I have some time, I go to the task, do what I was supposed to do, then close the task: out of sight, out of mind. It works as a nice "to-do list" in that fashion.

Still I rarely go over 6 windows. I like to keep it as clean as possible, giving the satisfaction that I don't have tons of things that I should be doing.
