no, you can't access something further than the recent 6 (well you can, but i think its a 2.2 mod on N1, haven't seen it anywhere esle). You don't close an app unless it has the option in menu, which kills the process. Otherwise, the app is set in a paused state, ready to be recalled until more apps pile on top of it, or enough time has passed where the system doesn't need to run the app anymore. App switching is done by holding down the home button and the last 6 apps show up. Sure it may not seem as convenient as the pages, but with widgets, you don't really need to load a full app. They aren't just settings apps, you can use an ESPN app to get all your scores where you would usually need to open the browser or app for that (it is accompanied by an app if you want real-time gamecast), or stocks widgets (for those that follow daily), pretty much a widget exists for anything you want. I rarely open up any apps. There are even messaging widgets (highly recommend handcent).
