We don't need a new app so kids can do video chat, there's Skype and others for that. They like the ease if use. The problem is to tack in another data plan restriction removal to open FaceTime with AT&T and possibly others is the barrier.
I have a 4gs and can't use FaceTime over the cellular network without paying AT&T more money or losing my unlimited plan. So I don't use it.
All this comes down to the same conclusion the author had. There's a huge market in the term category. They have deep pockets by proxy of their patents. But parents won't drop that much more for FaceTime. Want to tap that market AT&T, Verizon, etc? Allows FaceTime on your network. And Apple, open iMessage and FaceTime so that it can be coded on Sndroid and everything else. Apple gets brand recognition ala "FireWire" and we get a service we want that there no reason to pay more for.
29.00 a month for unlimited texts. Insane. 90% of my friends have iPhones. But messages from my bank, pharmacy,etc go through a non iMessage service. Apple needs to open up the protocol and allow an API gateway so regular SMS messages can get through. Then we can all dump the unlimited text plans or the 30 cents ala carte text plans.
