There are a lot of things this phone has and does, that would have turned me off if it didn't have them or do them, but the main reason I was initially interested was actually because of the high end DAC and amplifier for headphones. I am an audio enthusiast and the high end audio of the phone is what made me buy it. If it didn't have a removeable battery or expandable storage, and a good camera I wouldn't have gotten it though. So there are a lot of reasons I was interested in this phone, and after a week with it it's pretty much perfect. The audio is insane and it's all around just a really excellent device.
