Hold on just a minute and think about what you're saying. Apple didn't implement NFC or an LED indicator light. There are a few things wrong with those two things.
Apple didn't implement NFC. Okay? Yeah, it sucks. Switching to Android isn't going to help you much. NFC compatible payment places in the states are few and far between with Google Wallet and other than that, there isn't much to NFC. Now, the notification light. I wouldn't have minded getting one, but honestly, it's something you learn to live without. I made the switch coming from my OG Droid to the iPhone 4. It was a forgotten feature after two weeks.
About the rest of your post: You're correct. Android did have LTE and picture while taking video implemented before Apple did. Only thing is, it's implemented poorly. Take LTE for example. It's a great feature, but it's implementation inside of the phone required a lot of space being used up by the voice+LTE radio chips. Not to mention that LTE on Android phone's obliterated battery life. Apple decided to a wait a year for the chips to mature, for them to become combined instead of being two separate chips, and for the chips to become more battery efficient. In the end, Apple's implementation is best for many reasons (battery life, space inside of the device, etc.). I've never used the picture while taking video feature on an iPhone or an Android to make comparisons with that.
Apple may have taken longer to adopt these technologies, but in the end, it was for the better. Also, don't forget that right now Apple is the only one using dual-core A15 chips in the iPhone 5. No one else even has them developed on the mass scale that Apple does. That in and of itself is reason to upgrade.
TL;DR: Android is great in that it implemented technologies early, but is poor in that those technologies were new and relatively untested. Apple is great for waiting on those technologies to mature, but is poor in that had no one adopted the 1st gen chips, no further development possibly would've gone on to lead to the more mature chips.
