I'm not quite sure I agree with you on this list... But to me a "minimum" I consider essential to turning on and operating the device - not necessarily with all the bells and whistles. For example: HDMI isn't a minimum - sure it's nice to be able to connect an external display, but as a handheld with it's own display, you can survive without it. Same with SD cards/eMMC; a minimum to me would be one form of storage. Sure, the device will physically support more slots, but as long as some form of storage is available, it'll work.
