Why I would buy a N4: Wireless charging, after getting a tablet with it the convenience is now mandatory.
Why I would not buy a N4: No removable storage. I don't trust my data in the hands of a cloud provider, I want it on my phone where it is completely under my control.
Wireless charging was one of the reasons why I got a Nexus 4. It's a shame the stock wireless charger is so terribly designed though (no adhesion and unnecessary angle). Judging by the reviews it's gotten, looks like I'm not the only one who hates it.
Why is it a shame that you dislike the "official" charger? The N4 uses the standard Qi charging protocol, so you can get pretty much any charger you want.
I've tried a bunch of Qi chargers. Samsung's official S3/S4 charger is my favorite. They cheap out and don't include a USB cable or power supply, though, so you have to buy those separately. (Anker sells one on Amazon that does include a power supply that works great with the N4. Works very poorly with the S4, though, which just goes to show you how flaky random Chinese imports can be, even if you pay $50 for them.)
If you've got a kid, especially a young one, 16GB isn't enough for pictures and video. Not even close. My niece has filled her 64GB iphone many times over with shots of her kid. I'm sure there are tons of other use cases too.
"Isn't enough for pictures" really depends on the frequency that you offload photos from the phone.
Personally, if I'm storing important memories, I am NOT going to trust a loseable, breakable thing in my pocket to be the final resting place of JPEGs.
There are so many obvious flaws in that statement, here's two:
1) The assumption that the person who owns the phone owns a computer, rather than borrows someone else's when they need it.
Modern phones have hdmi outputs, and work with bluetooth keyboards. It is entirely feasible for the average person to use a high-end phone as their primary computing device. Especially with the carrier subsidies making the up-front cost so low. This will only become more common as phones get more powerful.
2) When you've moved the data off your phone it is no longer immediately at hand.
Flash storage is cheap and only getting cheaper, leaving off a micro-sd slot is all about pushing a cloud-storage paradigm rather than letting the user decide.
128GB cards are widely available.
The spec is good for up to 2TB, so it is only a matter of time. Meanwhile carrying a couple of extra cards tucked into the case of the phone is basically no effort at all.
Isn't there some sort of OwnCloud client for Android? You could use that as your storage solution, hosted on your own machine which should be completely under your control.
