GOD this just goes to show how TROLL you are!
first of all, your post which i argued talked about the iPhone not being smart enough for a smartphone! and now you are here saying you are not really measuring the "smart" factor of the phone! Jesus then why use that word then?..and no i don't know everything, it just feels like that coz maybe i offended you..
and now it's just your mere personal intuition..completely different from how you stated it in your previous post..
just say in the screen size department then if that's what you wanted to get across coz i completely understand that..
now to stay on topic, the iPhone 4s is definitely worth buying if you previously owned an iPhone 3G or older model, but the ones with an iPhone 4 might opt to wait for the iPhone 5 though (my opinion since i have an iPhone 4)..
