Maybe you should read what I said. It wasn't up for discussion. Everyone I know uses LINE. they have all sorts of devices. LINE is universal to all, no matter which phone you have.
It doesn't matter what features LINE has. It matters that everyone is on it. Every student, mother, teacher, everyone. Even the school director. Everyone. So even if i had an iphone, i wouldn't use iMessage. I had an iphone and i only used it with my mom.
Especially since iOS is so limiting. If I'm chatting with someone in LINE and they sent me a picture and I want to send it to you, on my Android I would just hit the SHARE button and send it to any app I want, but on the iPhone if I'm chatting with you on iMessage and someone else in LINE then I would have to save those pictures then open iMessage then search for you then browse the picture and attach it. It is retarded. That's one of the reasons I love Android. I get things done much faster.
So for iPhone especially its better to just stay on LINE instead of using iMessage and then jump back and forth between chat apps. It is easier to keep everyone in one place.
If you use it and everyone you know uses it then congratulations to you.
The point is, you go where your friends are. If everyone you know left Facebook and went somewhere else you would just follow them. You wouldn't stay on Facebook and talk to yourself.

My iPhone 4s (belongs to my wife now) has a loose power button on top. Since I took it out of the box. I never thought of it as an issue though.
My iPhone 4's home button died after about 8 months. I got the 4s after that. The iPhone 4 was the worst phone ever released by apple.
Just flat out disagree on the iPhone 4.
