The 4s is not a bad purchase for new iPhone customers or people upgrading out of the 3G or the 3Gs.
Not sure why everyone is all hurt-butt over the announcement. Did you all really expect an iPhone 5? That's not how apple has done things. 3G---->3Gs
It'd be foolish of them to come out with a totally new style of body phone wise, as in ALL of the cases, docks, mounts, everything, would need to be remade. That would only piss you off (the iPhone 4) as an old user because you would have a difficult time finding anything bits and bobs to go with your phone.
Oh well, dammed if you do, dammed if you don't.
I am just disappointed that's all the put in the phone. How long has it been? 16 months? And all we get is the iPad 2's processor? A slightly better camera?
I am honestly bummed that I won't get siri on my 4. Or so it seems.
But iOS5 will run smoothly on the 4 and will only make it better, and it will get iOS6 I am sure. So I am not worried about the 4s, nor am I burning down buildings to try to get it.
