What I really want out of iPhone OS 4 is foreground apps, not background
It’s occurred to me that my main usage pattern for the iPhone is to have some app open, and then have to quit it to go do something else for a minute (look something up, respond to a messge, etc…), and then go right back to what I was doing. I don’t care as much about having apps run persistently in the background (though I won’t say no if apple comes up with a really elegant way to do this while avoiding all of the nastiness of process management, which I DO NOT miss at all), but the ability to jump to something in the foreground and then right back to what I was doing without having to quit the first app and restart it would be very welcome.
