1) dont keep actives (i checked it)
2) background process limit to 2

I'm curious about "Don't keep activities", myself. If I understand it right, that means every time I exit an application, that application will be closed, correct? If this is right, does pressing the home button count as exiting the app, or does the "back" button still the only thing that counts as actually exiting?

An "activity" is not necessarily an app. An activity is anything that a user interfaces with. So a simple text box can be an activity. Most likely, this option is keeping memory clear of activities so that the phone forces a reload into the memory every time you execute a command. I'm unsure if this will be a net gain of battery life or not. Going through all of the onCreate() methods of every activity ever single time could be a bit of a battery drain.

Or I could be completely wrong about what this developer option means.
