Or, go buy a PRE, who's notification system is so far more advanced than the iPhone that there is really no comparison.
There needs to be a collection place for notifications where one can go in and look at ALL notifications from ALL apps, then click on the notification to go to the item in that app.
Of course, being that this is probably the best thing Apple can do, they won't even hint at it for several months, years. I'm almost positive they hold back on us.
