I have been going back and forth about getting one. The longer it takes to become available in the play store again, the less likely I am to get one.
Coming from a VZW Gnex, the N4 doesn't really over much as to the things I care about in a phone. There's only 3 things I really care about. Most important to me is screen quality, then build quality, speed of the OS, and then price of service.
Screen Quality: When it comes to screen quality, what I really want is an HD screen with low black levels. I just don't think LCDs are there yet when it comes to black levels and viewing angles. I have to admit, that during daytime, looking straight on, the N4 would probably look better than the Gnex. But I've had a thing for Samsung's amoled screens ever since I've had the Galaxy S Captivate. I can't stand blacks that look grey and don't blend right into the bezel of the phone when under dim lighting conditions.
Build Quality: The N4 has better build quality, but this advantage is nullified by the fragility of the glass backing. I don't drop my phone a lot, and I've never broken a phone, but I do drop phones every now and then, and would end up dropping this one. What's the point of the fancy glass backing if I'll have to cover it up? Even if I did cover it up, I don't feel like the backing would be safe. Rather than dropping the phone, the real problem is that I carry my phone in my pocket and a lot of times my gnex will hit door handles, the corner of tables, or stair rails. I'd like to see a nexus built by motorola, something sturdy, but still sleek (although I do think motorola phones can be a bit to industrial looking at times).
Speed: The N4's processor is faster than my gnex, but I already have 4.2 on my gnex and the OS is basically just as fast and buttery as the N4. And I don't play graphic intense games on my phone either, I save that for my N7.
Price of Service: I could save $200 and buy a GSM gnex instead and save money on my plan without having to buy the N4. If I switch to t-mobile's $30/month plan, I can save $45/month, or if I switch to straight talk, I can save $30/month. I do think that LTE is a bit overrated, and in my personal situation anyway, I cannot get LTE at work, so 90% of the time when I want to use LTE, I'm actually barely even getting a 3G signal.
There are a bunch of pluses or minues that I didn't mention here that some people might care about. I don't really care much for picture perfect camera quality on a phone. Just about any decent smartphone has a decent camera that would be good enough for me. As for storage space or removable battery, the only time I removed my phone's battery was to install the extended battery. As for storage space, I have a 32 gb gnex, but I take advantage of google music's cloud service so I don't use much space on it anway.
TL;DR
For the things I care about, the gnex does them just as well as the N4. The N4 has good screen quality but not low black levels, fast processor speeds that won't help with the way I use the phone, good build quality but is fragile, and low cost service plans which are obtainable with the gnex.
