Android through and through. I've had a Galaxy SII for over a year now and it's worked perfectly for me. The biggest problem I had was the battery suddenly overheating the getting drained. It was fixed by taking the battery out, cleaning the phone, and putting it back in. Works like new. Voice recognition is perfect, the apps are more than fine for what I need them, the speed is amazing, connectivity is good and the dual-microphone it has filters out any and all noises when I'm talking to someone. I've had people ask me mid-conversation where I was and when I'd say I was at school or on the street, they wouldn't believe me because there was absolutely no background noise. So yeah. I'm not planning on switching to an iPhone anytime soon. In fact, I plan to upgrade to S4 once it comes out. Samsung did a fantastic job with the Galaxy series and I really don't see what Apple could possibly offer me to make me want to buy their phone.
