It's not nonsense.. everything I said is in my opinion an accurate assessment. If you need a high end camera (is it?) in your phone, then this is a logical upgrade for you. For the general masses, it's just some pixie dust.. I'm sure you could ascertain from my tone that it didn't come as a surprise to me.
I too have owned every iPhone, including the 3 (I've also owned every iPod, and almost every revision Apple notebook, as well as iMacs - and earlier desktops as well). The 3 was frustratingly slow, so I was happy to upgrade to the 3GS for the speed improvement alone. The 4S is to the 4 what the 3GS was to the 3, I'm not disputing that. Personally, I find the 4 to be very quick. I suppose it could use a bit more oomph, but I'd rather wait til a hardware revision comes out before spending any more money.
I like Apple products, and am more than happy to upgrade when I feel it's logical to do so. I don't need a better camera and I certainly don't need to play FPS on a tiny screen. Admittedly, I'm not all that familiar with how much Siri offers, but from what little I've seen of it, it doesn't interest me. If the hacker community can find a way to make it work on a Jailbroken 4, I'll check it out.
For most people, I can't see this as a necessary upgrade from the 4. But who says one needs any of this stuff... if you want it, and can afford it, go for it...
