Again, so what? The time it takes to load most apps is not significant. The developer guidelines dictate that the programs be written in a way that gracefully manages opening and closing them all the time. (Or somesuch, anyway!)You've got to be kidding me. No really. Push notification? The Pre has fantastic multitasking that allows you to use 12-15 apps (ANY APP) at the same time, PLUS unobtrusive notifications, and Apple decided to use push noitification to match everything? How does that match multitasking among all apps? Hell you're still killing apps everytime you go App>Homescreen>2nd app>Homescreen>1st>app>Homescreen>3rd app.
The push notifications will do what I would keep apps open for, telling me if there's a new IM or other updates. Palm has solved the whole app handling better, but the actual difference in usage should be neglible. Depending on 3rd party app quality, the additional battery drain from multitasking probably isn't.
