I agree about the LTE. For me it is overrated. I am 22 days into my billing cycle and have used 165MB of data. If I had LTE I doubt I would have even noticed it. I don't deliberately conserve mobile data either--I just happen to be on wifi most of the time.Overall a good review, although I feel you placed too much merit in the LTE. Three points just for lack of LTE? Dang. I'd have done one, maybe two MAX.
I wish you did a price point comparison. Opinions there would be interesting, because while the iPhone is much more expensive off contract, there are cheaper with contract options. The Nexus 4 is simply an off contract device but quite impressive. It's a premium device that can even be used on pay as you go network for a non-premium price.
Regarding the price.... I think it is the non-contract prices that should be compared. Reason being if you are a non contract kind of person those are the prices you will have to pay.
If you are a contract person you still can't say the iPhone 5 is cheaper or the same price. Since you would be tied to a contract for an i5 you might as well still take advantage of a contract phone (if you buy the Nexus 4). I don't think I will be leaving AT&T, for example. If so there is no reason not to take advantage of a subsidized phone, even just to sell. So I can buy an iPhone 5 for $200 and turn around and sell it unused for likely twice that. That reduces my net cost of the Nexus 4.
