There's nothing revolutionary about it, nothing new & exiting. It's just a bump in specs. The change from the iPhone 3G to 3Gs was a little more "exiting" because the performance improvement really made the phone a better user experience. The current iPhone 4 is plenty fast, but then I don't play games on it.

So if they had used UPS it would have been better?
My thoughts precisely. When I was shopping in the store for the 3GS, I compared it side-by-side with the 3G and the difference was BIG. It felt almost 2x faster all around. I also compared to Android, and back then, Android was garbage. Just terrible, and in no way comparable to Apple. I got the 3GS and was blown away by all the features (partly because it was my first smartphone). I loved that phone to death.
Then, when I compared the iphone 4 and 3gs side-by-side, although faster, the difference wasn't as pronounced. Sure, many improvements, but I just didn't feel compelled to upgrade. By that time, I was a little bored with iOS and interested in all the new improvements in Android, so I switched just to give it a try.
Now, I am waiting to come back to iOS, and was hoping for 4G and a larger screen or other improvements to bring me back. The 4S announcement didn't do it for me, and so I'm going to wait a little longer on Android until the next iphone model comes out. In the mean time, Android may come out with something (Nexus Prime) that will convince me to stay even longer.
Really do miss all the little things about iOS/Apple that make it great though. But right now, Android serves my needs despite the lack of Apple refinement.
One other thing to note if you are all comparing in-store Android models to the iphone:
Out of the box, no question, iphone is better. Many Android phones are still clunky with the manufacturer launchers/bloatware. However, if you want the Android experience I get (and that I use to compare to iOS) you have to root the phone and flash custom ROMs/tweaks. Once you do so, the experience is nearly as fluid as Apple, and in many respects, better. That in itself is the problem with Android: you have to know what you are doing to get that great experience whereas with Apple, you just open and go.
So for people bashing Android for not being close to the iphone, I can agree with you to some degree when speaking stock-for-stock. But with customization, Android id pretty close in overall smoothness and better in some respects (customization, options, etc.)
