Adding to that, slimebeast, I never said it was a phone. It has 3G just like tablets. Granted with Google Voice or Skype it could be used a phone, with a bluetooth headset, but not too many people would do that.
Ok, cool, it's not a phone (I don't want it to have phone cabapilities since I don't want it to become too successful lol).
Your analysis though, I think it makes sense. Sony tries to please all the different markets segments.
