I noticed nobody mentioned this and deaf people need to know this; there's no vibration on iPad. It's a major accessibility issue for me. I don't know if it's hardware or software limitation and I hope Apple can fix this (I already sent them email about this via Feedback, dunno what else I can do beside emailing steve jobs...i'll do that next). I have seen some people saying it's not needed on iPad, it makes sense on the phone but majority of people don't realize that it's needed by deaf people. We have no other way of getting notified of new incoming emails, text messages, push notifications and so on if we can't even hear the sounds in the background. I was reading macumors and when i quit safari to switch to another app, I saw that I got 20 emails. I now have to carry my iPhone with my iPad to get notified of new emails (via vibration).
