Shadoe Huard responding to this post by me:

If you think iMessage is only a handy bonus, you’re missing the larger picture.

He says that iMessage will be a “game changer” — it could be, but not in it’s current form. Currently it is just going to be a nice bonus for being an iOS users. What would make it a “game changer” is if one of the following happens:

  1. It is integrated into Mac OS X.
  2. It is opened up so that other platforms can use it (Android mainly).

No matter how popular iOS is, it won’t every be on 100% of devices, thus it becomes hard for iMessage to be a wild success in the same way that Text messaging is. If, and only if, iMessage becomes universal, that’s when it will really matter.
