Having had only iPhones since the introduction of smart phones, I was ready for a change. I wanted something that would allow a much greater level of customization, give me a larger display, and provide expandability for memory. With the Galaxy S3 I wasn't let down. The S3 is loaded with features and has an incredible display. It's micro SD slot allows me to keep tons of stuff (music, audio books, movies, etc.) right at my fingertips, which is very important to me. The ease of changing batteries was also convenient (and sadly necessary). As far as individual features that I like and find useful, there are too many to go into here. The only serious gripe that I have is the rather lackluster battery life of the S3. This, I'm told, has been improved upon in the latest iteration in the Galaxy line and that will retain my brand loyalty. So, all things considered, I can honestly say that I will be upgrading to another Galaxy soon.
