Mine is covered back and front. People who see me with it would never now it's an iPhone. So definitely not about the branding for me. I just like the OS. I also like Android but choose iOS because of the regular updates.
Not all iPhone users are fanbois or sheeple you know; normal people use iPhone or Android, whatever they prefer.
Ha, I did exactly this. Went to a 6s after my 6 packed up primarily due to the headphone jack not being available on later models but also the 6s was much cheaper and I'm not really interested in having the latest and greatest. To be fair, all the manufacturers are messing around with their high end phone prices.
