So far so good with the Nexus 4.
A couple of things I don't like. The SIM tray is real flimsy and a micro SIM is a real tight fit. The Google Contacts server is terrible. It's up about 50% of the time. I got real tired of getting a "try again later message" doing contacts from my PC.
It had a good assortment of applications. One it was missing was a simple note/memo application.
I've installed, Amazon application store, Amazon MP3 cloud service, Air France, Flickr, MLB at bat, notepad and TuneIn radio pro. Which is all I really need. I didn't get charged for MLB at bat or Tunein radio pro from the Amazon application store, because I purchased them for my Galaxy S2, so I am sitting at 5.2 GB of available space, which is fine.
The camera isn't bad at all. It's no better or worse than my Galaxy S2. Bright day light shots are fine. Don't even bother with low light or night time shots. It doesn't come close to what my Nokia N8 or my wife's Nokia 808 can produce.
You have to give Google credit for updates. I've had numerous updates for Google applications and it's running Android 4.2.1 now.
