I will miss iOS , it was perfect for my requirements, simple and fluid. ( Not saying Android is not, but there will be learning curve for me )
Currently I have iPhone 4 but I am not impressed with iPhone 5 .Going to buy note 2 in March.
Main reasons for me to switch are
1. Bad build quality of iPhone 5 - Yes it looks lovely when you take it out of the box but gets scratched easily after couple of weeks of use. My work iPhone 5 has twice as many scratches than my personal iPhone 4. If I'm paying premium price for a phone then I expect it to have premium quality as well.
2. Got fed up with small screen size of iPhone , half inch extension on iPhone 5 wasn't enough for me.
Above reasons made me look for a new phone and I am set on note 2.
I am a die hard Apple fan so this is a big move for me. Apple really missed a trick with their choices of screen sizes. I would have settled for an iPhone 5 if it had bit more screen size and decent quality outer surface.
ps- I develop iOS apps for living so it's safe to say I am not going to be popular at work after this switch LOL .
