1. I buy based on aesthetics. I do not upgrade every year. I do not sell my phone to pay for the purchase of the next one. I do not buy based on need, I buy based on what I want (screw need). I live with my phone for 2.5 to 3.5 years and after that it moves down to become a media device for however long it lasts.
I want to like the device I am constantly looking at for that entire time.
2. I don't use cases. No slapping a case on my phone. I hate case, I abhor them and I refuse to use them. You and anyone else who likes/uses cases can slap one on if you like. I repeat - I HATE CASES.
So, slapping on a case is out.
