So, good point. Four-inch displays are nothing new in smartphones.
Then there's LTE, the fastest wireless data standard available. LTE has been around for over a year, starting with HTC's Android phone that launched in spring 2011. Since then, nearly every premium non-iPhone device that's launched ran on LTE networks. It took a year and a half for the iPhone to achieve that.
So, good point. LTE has been around for an eternity by tech standards. It's a bummer Apple didn't include it in the iPhone 4S last year.
As for what Apple left out of the iPhone 5, there's Near Field Communication and wireless charging. NFC chips let you make mobile payments with your phone and swap content with other devices just by tapping them together. Wireless charging lets you charge your phone by resting it on a power pad. (We saw wireless charging last week with Nokia's new Windows Phone, the Lumia 920.) Both of these features are increasingly becoming standard in smartphones, but Apple didn't include them in the iPhone 5.
