Even the two (old and new) are really the same thing to a lot of us...
I remember seeing a Nokia ad one boasting of their 83 kinds of phones. I was thinking how dumb that is, since they have 3 basic kinds (cheapo, blackberryish, and iphoneish) and having been through a few of their phones, know they run towards the unspectacular. If they would just make one each of the three kinds, maybe they could offer one really good phone for each type.
Apple's making one really good model is a really good model.
