Ok, this is going to sound really silly... but I was just reading about all the people in the iPad forum complaining about their pages in safari reloading. Of course this is due the 512mb of RAM and the way the OS is designed to free up any older space whenever it needs more space. That got me thinking... I know that Lion is being designed to run more iOS-like, where the OS is in charge of handling RAM. Does this mean that with Lion is there the potential to have the same situation? Obviously Macs have more RAM so the chance of it happening is reduced. Or along those lines, say I have itunes (or any app) open and "running". If I run enough RAM intensive apps over the next few days without again using iTunes, would Lion ever get to the point where the window would actually close and shut down the app? I know that if you don't have any windows open the app could shut down, but what about if you leave the window open?
