After owning an iPhone since launch in 2007, I got sick of it. It was so boring and plain. When they announced the iPhone 5, it was a deal breaker for me.
Today, I upgraded to the Galaxy SIII. Holy crap do I love this phone. I've only had the phone for maybe 3 hours so far but it's amazing.
Finally switched over to the dark side
I'll probably root the phone eventually, not sure though.
