Yes, Yes, I see that already

With iPhone 3, whenever I opened the phone enough to see the message counts for my calls and messages, it would clear the notification automatically so the alerts wouldn't keep appearing.  I already knew who was calling from the alerts.

With Android, I have to open the calls or messages apps specifically to clear the alerts.  I find this annoying.  That notification light can be blinking all night long until I have the energy to open up the apps rather than just checking the phone.

It's like somebody actually tried it first, before releasing the software.  I consider that that the first step toward decent design, but often and strangely a step that never seems to have been taken.
