First I want to start by saying that I have had an iphone since launch date of 2007, I always loved my iphone and I have bought every generation of it including the iphone 4s. Slowly I have been getting bored with the iPhone, when I saw what was coming with iOS 6 I was disappointed since I thought they where going to introduce really cool things that the OS would do. I then saw the keynote from Samsung about the Galaxy S3 and I was blown away. I thought this is what the iphone 5 should be.
I ended up selling my iPhones and bought a galaxy for me, my wife and my son. We love the phone. We have had the phone for over 1 month now and its amazing. The screen is awesome, the battery life is very good for me, it last me almost all day. The fact that I can swap out the battery is great. I have used other android phones in the past and they suck, this one with ice cream sandwich just works. If you are looking for a change than this is it.
After looking at the photos of what the iphone 5 is going to be like I feel I made the right choice. I don't want a phone that is just longer it needs to be wider, apple should have made it at least a 4.3 screen.
The only complaint I have about this phone is that when I put it a holster it starts getting hot. Most android phones do that and I think its because since it has real multitasking the apps stay running all the time unlike the iPhone where the apps are paused.
I can tell you that I can do things on this phone that the iphone does not allow. That alone was getting me on the fence. Lastly this model has 16gb onboard and I was able to buy a microsd card with 64GB, now I have 80gb. I love that the storage is expandable.
