Yeah, this is one of those threads again. I need some buying advice, largely just to bounce thoughts off of people. I'm looking to replace my Samsung Vibrant (Galaxy S for T-Mobile). I've been waiting to see what came out of Google this fall, and the Nexus 4 seems to be it. I'm not completely sold on it, however, largely for reasons that are now well-known around these parts. I was hoping for something with a keyboard and a screen that's not large enough to qualify as a tablet. However, it seems The Powers That Be have decided that high end phones aren't high-end if they aren't too big to fit in your pocket and lack physical buttons. I am not happy about either development but I've resigned myself to that fact. I'm on T-Mobile, and there's really only 2 good high-end phones they offer right now: Nexus 4 and Samsung Galaxy S3, which AFAIK are not all that far off from each other. To the Nexus 4's favor: Both are too big, but as above I've accepted that I'm not going to find a high-end Android phone under 4.5". The N4 is slightly better in that regard, though. I was really burned by the utterly horrific GPS antenna on the Samsung Vibrant. I haven't heard of the S3 manages to avoid sucking in the same way. N4 has the nexus mojo and upgrade potential vs. Samsung, who, after the Galaxy S upgrade debacle, I don't expect to ever speak to again after the sale. (Other S3 owners, is that true?) N4 has stock Android, although I understand newer TouchWiz versions suck less than old ones. Can I at least get stock PIM apps? (The PIMs on my Vibrant are godawful.) N4 doesn't have LTE, blah blah I'm on T-Mobile, so HSPA+ is what I need anyway. N4 is brand new, while the S3 is more than half a year old. Which shouldn't be a big deal, but you know how quickly phones move in this market. To the S3's favor: It is a flagship device, so if it were anyone but Samsung I'd expect it to get lots of support. (Anyone with an S3 have experiences to offer? Mostly I'm interested in clean OS upgrades...) It's been out a bit, and I've not heard of any serious kinks. Unlike the Nexus 4 which seems to be having a lot of growing pains out of the gate, based on the news postings here. This is one of my biggest worries. It's actually possible to get right now. Storage: N4 maxes at 16 GB, S3 at 64 GB + microSD. Of course, I've not filled my 12 GB Vibrant yet, but I'm still wary of limited expandability. The non-removable battery of the N4 makes me worried, not for replacement purposes but because I've had to "battery reset" my Vibrant a bit too often; I don't know how to recover from a hard crash other than that. Let's be honest, SAMOLED's just damned pretty on screen. Mini-SIM on the N4 may make it more difficult when I travel, as I travel overseas once or twice a year these days and sometimes prefer to get a local SIM. Those are usually standard-sized SIMs. I think otherwise the two are largely comparable in terms of guts. (Both quad core, both NFC, etc.) S3 owners: How is battery life like? My main uses are GPS, web browsing (I'm a web developer), Twitter/email, ebooks, and games. My heaviest use is at tech conferences, where I tend to pound the network connection rather hard, making my Vibrant's battery curl up in a little ball. Anything else I'm missing? Any other wisdom or experience to share? Help me spend money!
