Re: like fitting wheels to a tomato....
We all want ... removable battery, SD card slot
No we don't. Some people do.
I personally have no need for a removable battery (and attendant case design compromise) or SD card slot on my phone. I suspect the same is true for most users.
SD slots take up space, provide an opportunity to collect dust, don't guard against poor quality cards, and don't partake in the hardware encryption that is imposed on every other file on my phone. I'm glad my phone doesn't have such a slot.
