It has camera and removable batteries, and it will be airgapped.
The removable battery is not proprietary or even similar to a phone's battery, though. It simply uses 2x standard AAA batteries. If anything, that should make it cheaper than using a more expensive rechargeable battery.which means that the ideal place to hide this device is right in the box with children's toys🐱💻
Until your child decides to dunk it in their juice, take it in the bath, or leave it outside in the rain.

Yeah, and I stand by that. As someone who likes to carry a hardware wallet around in their pocket, a device which is 8 times larger in volume than the Nano S or the Trezor One does not fit my use case. But hey, YMMV.
