My Nexus 4 is still my favorite form-factor/experience out-of-the-box for my "I just need quick access to my email and sometimes a camera-phone/video" purposes. It was exactly what I wanted in a phone - $200 - no contract, minimalist, no junkware, hackable out of the box, large enough to one-hand for my average male 5'10 hands, decent battery life.
Granted I actively try to stay away from technology when I'm not working - i.e. I mostly use it as an equivalent for a doctors' pager in case anything catastrophic happens. It's mostly used for GPS (which is pretty phenomenal), to listen to music, and track my speeds/path when I run, etc) so I'm certainly not the power-user who needs 16gb of RAM to support 100 active Safari tabs.
When this breaks, I'm going to upgrade just out of necessity at some point at which point, assuming this isn't cluttered with junkware it's one of the few phones I'm entertaining (since there's no real viable 'open' phone on the market right now, as far as I can tell). The alternatives I'm considering is going for one of those Asian vendors (Lenovo, Xiaomi, OnePlus, Huawei). My Euro and Asian friends say they're all are putting out quality (e.g. Samsung level) stuff with no contract lock-in .
