I use it fairly regularly, both my girlfriend and I work in theatre and are therefore away from each other fairly often....we use it to make each other smile with a photo...yes, we could use email, but i for one like to feel the buzz in my pocket whilst i'm rehearsing and have a sneaky peek when the director is looking the other way .....
It's not a dealbreaker for me because hopefully it will be coming, but if not, i have an old k800i somewhere
