So, 18 months after launch, how is your Nexus 4 hanging in there? Assuming you still have it, of course; seems a lot of people have moved on to new devices. Mine is still as beautiful as ever, although the headphone jack hasn't worked since last year, battery life seems to be inconsistent and slowly trending downward, and I notice a touch of lag and stutters now and again. The last could probably be fixed with a factory reset, but I'm too lazy. The others I've learned to deal with or work around.
