I had been needing to replace my GS3, which I managed to drop and crack the screen something awful. I enjoyed the S3, but I just felt like there were way too many gimmicks in the UI, and I kinda got annoyed with it. Back when I ordered it, I was torn between the Galaxy and the Nexus, and went with the Galaxy. Now that I need to replace it, I decided to pay $100 more than I would for an insurance replacement and try out the Nexus, especially with it being unlocked. Out of curiosity, I asked at T-Mobile about getting one now that I'm switched to their new plans, and the down payment they wanted from me for the Nexus 4 was only $50 less than the new price on Google Play -- and I woulda had to keep paying on it!
So, long story short, I made the leap to the N4, and I'm waiting for it to get here Monday or Tuesday. I know the next Nexus will be coming soon, but I figure I'll enjoy the pure Google experience on the N4 for the great value it is. So glad I found out about the price cut!
