Reviewers don't understand how the BB works – Boogie Board Jot Review

I have yet to try this app, but I want to comment on some reviews below that want to be able to transfer sketches by bluetooth or SD card. These don't understand how the Boogie Board works. Images are created by applying pressure to a liquid crystal display. They are electronically erased. They are not digital in any way, so there's no way they could be transferred to another device digitally.
