Had high hopes for the NX4, but lack of storage and LTE is a killer.
LTE:
For those saying the difference between HSPA+ and LTE is only a few seconds....lolol. The difference is immense. Especially when downloading, streaming HD videos, tethering, etc. If you have LTE in your area, don't skip on it. It's definitely a feature worth having on your NEW phone.
Storage:
16GB max? this is a huge problem. Not everyone has unlimited data. Furthermore, google music is a joke. Poor UI, constant crashes, slow, etc. Oh yeah, it also kills the battery because its a streaming service. That right there cancels out the "amazing" battery life of the NX4. I'm glad i picked up the 32GB iP5. It's nice having all my music/videos/etc on me at all times.
I really wanted to give android another shot (RIP SGS2). I have heard nothing but positive things regarding jelly bean. The hardware just isn't there. Maybe next year
You say LTE is important for streaming HD movies and tethering, but go on to say that 16GB isn't enough because not everyone has an unlimited data plan. That is a bit of a problem, no?
If people don't have enough data to stream, why does it matter if they can stream at 50 Mbps? Same goes for tethering. I probably use many GBs of data per day on my laptop just browsing the web. Why would LTE speeds matter if I don't have the data to support it? It's a fact that most people don't have unlimited data and that most people actually have relatively low amounts of data.
As for the HD streaming, it doesn't make much of a difference. HD movies on iTunes, Netflix, and many other places do not provide you with full bit rate streams. On iTunes I saw an article that said most streams are like 6 Mbps for 1080p and 4 Mbps for 720p. HD just means resolution, not bit rate.
Aaaaaaaaand, the iPhone has a less than 720p screen in which you can't even see pixels, thus why would you even want a 1080p stream?
Aaaaaaaaand, with respect to content, the Nexus 4 can just download torrents directly to an Android phone. You may be able to stream your content fast and download from iTunes faster, but you have to pay for it while for HSPA+ people on a Nexus it's free
