A:AnswerNo built in card reader but it may be possible to plug an external sd card reader into the usb-c port. Alternatively the device can be synced to iCloud encrypted storage for a monthly fee.
A:AnswerThe iPad is identical to your iPhone. It also has the finger print where the power button is located. Although there is no face feature to unlock your iPad.
Your iCloud will help you sync all your apps from your iPhone to your iPad. Takes less than 30 mins.
A:AnswerI have both the iPads and iPads Pro Bluetooth connected to mine. They both work perfectly.
I tried to connect a pair of wired AirPods. Even when using a “lightning” to “C” adapter on a wired pair of Apple EarPods , I could not get them to work.
So I guess you are limited to bluetooth connected AirPods. I have connected a pair of Miniso, Bluetooth over the ear pods, which were a snap to connect, and they work perfectly. So it may be likely that other brands of Bluetooth connected EarPods, earphones or headphones may work as well.
