I am currently an iPhone 4 user. I have never used a smartphone other than an iPhone. I wouldn't say that I am unhappy with the iPhone, but I decided to switch to a Nexus 4, which I will receive today. I decided to go with Android for one simple reason: I wanted a bigger screen. I decided that to me all other pros and cons of iOS vs. Andriod were not as important as screen size. Some backround information on my pre-switch status: I currently run my iPhone 4 unlocked on Straight Talk. The Nexus 4 appealed to me because it is also unlocked and because of the price. But price was not the deciding factor as I also considered an unlocked "T-Mobile" iPhone 5 or a used 4S. I just want to pop in my straight talk sim and go. I also wanted a phone that would certainly get the next Android update in a timely manner. I am in an all Apple household. Both my wife and I use Macs. We have 3 AppleTVs. We use an Airport Extreme and an Airport Express. I have an iPad 2 and an iPod classic. I sync with iCloud. I use iPhoto and iTunes. I use Photostream. I have purchased many iOS apps over the years. Frankly, being so entrenched in the iOS/Apple ecosystem is my main concern about making the switch. But reseach I have done here and on other sites leads me to believe that these concerns are easily addressed via Andriod or apps from the Play store. I do not play games on my phone. I use my phone for what most people do: web, email, phone, photos, video, streaming audio from tunein or Google Music, news apps, weather, etc. I don't use any niche apps, or at least heavily. I am not jailbroken. The first thing I will do is transition from iCloud to Google services for contacts and calendar. I will also need to do this on my iPad and Mac, but I used this setup before iCloud existed, so I am comfortable with that. I am already a Gmail and Google Music user, so I should be set there. I don't plan on immediately installing Android versions of apps that I currently have. Instead I plan to install them as I need them. I wanted to post this thread to share my experiences over the coming days to hopefully help others with the decision to switch. I will also be happy to answer any questions. I will post my initial impressions of the device after I get home from work and have some time to set it up.
