SD card slot? Do today’s devices need that?
Along with various advantages, SD cards also have some shortcomings which are encouraging manufacturers to remove SD slots from portable devices and replacing SD card slots with USB ports and internal memory.
It is all about business in the first place as the manufacturers want to reduce the complexity of portable devices by removing the detachable battery and replacing the SD card slot with more internal memory. This change not only reduces the multiple things attached to the portable devices but also increases the hardware price. Limited internal storage does not decrease the use of mobile data, but increase the use of cloud storage and online services, etc. where non-removable battery makes the devices disposable.
