What constitutes "nothing good"
Faster processor?
Better camera?
More memory?
What constitutes "something good"
Bigger screen?
I get the impression sometimes if they add all this new tech in an iPhone 4 box and call it 4s it is crap
But if they make the screen 4" and don't do anything else and call it an iPhone 5 it is golden
I think it's just due to the horrible design of the iPhone 4. If the iPhone 4's design was proper without issues, like the iPhone 3GS, then i think people would say that this is a huge upgrade. Because people are afraid the external design will be the same, they're saying that it's a minor upgrade.
