I have iPad and android phone (G2). I like the G2 notification, it helps me sorting out messages, updates, and such. But then again I don't miss it much on my iPad, because I do different stuff with it - I concetrate on reading mails there (or even newsgroups), rather than expect to be notified. But with iPhone I would love some notification system.
