It's not even that it's 4" it's the fact that it is just a stretched out 4" being as wide as their 3.5" devices.

Agree, I will wait until the next redesign and then see if it is worth upgrading to.
That might never come, look at the mac pro, imac, ipod...

The industry's maturing. Unless you think adding an inch to a display is innovation, I'm afraid you're not going to see any huge leaps like the iPhone 4, and if you do, you'll see them less frequently.
You only need to look at what's happening with Android to realize that... Someone (LG?) actually made a commercial promoting the ability to see a video and text at the same time. Or Samsung, and their heavy promotion of their NFC tech where people embarrassingly make their phones "kiss" to transfer data. Android's last 2 releases' most signficant features were essentially a Siri knock-off and Miracast, an Airplay clone, only 3 years behind.
Nfc is embarrassing? Lol being able to transfer data instantly is pretty cool to the rest of the world. Or do you not read consumer reports where they listed the gs3 number 1 and the ip5 number 2? Apple has a nice build quality but not much else currently.
