They REALLY need to revamp their notification system if they're going to do this!
Those pop up messages are way too intrusive and in your face, but the badges are way too subtle!
The
Palm pre's notifications rock, it pops up from the bottom but does not obscure the screen. You do not have to close them or anything, you can keep working as you get notified.
Android's notifications are in a clever and useful pull down menu. I'm pretty sure that when you get one it alerts you up top, then you can slide your finger down from the top to drag down a little list of notifications.
On the other hand,
Apple just pops a pop up straight in your face! And you need to stop typing whatever you're typing or reading whatever you're reading and deal with the pop up screaming at you. With badges though, you would have to scroll through all of your home screens to see if anything has a notification (if you turn off the annoying as hell pop ups). They need to take a clue from palm or google and revamp their notification system - especially if any app will be notifying us in addition to the apple ones!
