Marketing marketing, that's the way of the technological world.
I was wondering whether Apple has had these "new" features for a while. As many have mentioned, most smart phones have had MMS, cut/copy/paste, video recording, etc. so I'd be surprised if Apple released the iPhone without planning on releasing these features sometime down the road as it would be a bit of a gamble on not knowing if they would work in a multi-touch platform. Holding these features back and releasing them slowly seems to be a good strategy at keeping iPhone sales strong.
I'm in agreement with you. The viral marketing is working on me as I will be upgrading my iPhone later this year.
