So, I have been thinking of a really cool way they could implement iMessages with the iPad/iPhone combo. Using the syncing mechanism they are going to use to have all of your conversations between devices anyways, I feel like they could see if you have an iPhone on your account. Then from there, if you want to send text messages from the iPad, it would send the notification over to the iPhone to send the message - while syncing the conversation. Then, once a reply is received, it would be pushed back to the iPad. I am hoping sooner or later they implement this, because it would be really really sweet
