Have had to 3 and 4 and decided to order the 5, went to the store tried it out and messed with the Galaxy s3. Spent proly an hour their and decided on the iphone 5 mainly becaue its what I know and I have a bunch of itunes stuff and apps. Well went home and instantly had buyers remorse.
Went back to the store the next day, cancelled the order and picked up a s3. I love the S3 and dont regret it for a second.
The Iphone 5 was just more of the same and for most people thats fine and I thought that would be fine for me but the android platform is just more customizable.
