I’ve never recalled an ipods(the old ones), ipods(the new ones) iphones or ianything portable having an sd card slot
What tablet should I get?
They have an adapter that allows you to connect an SD card into it, but it’s purpose is for importing photos (straight from a camera). Apple were never one for removable storage in their handheld devices unfortunately. Like previously said, they prefer to just make different capacity versions (16, 32, 64GB).
