Re: Phone appearance
Cases also avoid some of the issues that making them built in would cause like plastic/rubber stuff getting worn out looking, and gross from oils from your hands etc. over months/years. Just take a look at some people's phone cases, and tell me that's what you want your phone to look like after a year or two.
No thanks. People who want a more durable phone without the horror of having buttons and ports slightly recessed can buy the ones built for that purpose. Oh, you don't like the lack of selection? Well I'm sure people who put all those cases with different patterns and looks don't want the lack of selection that would result from having built in cases in a handful of colors, either. Why should they compromise to give you the wide selection you feel you're entitled to?
The market has spoken, and people don't want phones with built in cases.
