When should I worry about available RAM?

[stanw]

Under the Running Apps, it shows that I have 1.7GB used with 712MB free.

1. The different apps seem to all show 1 process and 1 or 2 services. What does this mean?

2. Should I routinely go through these apps and quit/end them?

3. If so, at what point should I do this? Do you wait until performance overall takes a hit or when free RAM reaches a certain point?

Thanks.

Android has it's own way of dealing with RAM and running apps. For the most part, I'd leave it be.

There's a general rule of thumb that I like to go by: Free RAM = Wasted RAM
