I have read about google wave and it does seem to be the way forward. A real time communication dashboard showing all your friends and contacts status and current messages, latest news headlines, weather stock updates, web pages you like etc etc. To me this is almost like the next step in communication between people and brought to a portable device like the iphone it takes the phone beyond the phone- It really becomes an extension ot the owner. So to be simplistic if your email, sms, face book, twitter, phone calls were all displayed on one integrated window so at a glance you could see who was available, where they were, their last conversation with you etc etc. Why should texts and email be different applications it should be one user friendly integrated app. Not trying to overstate it but this is going to be huge and I hope apple sees the potential. On the tablet with a bigger screen the possibilities are even more exciting.
