It's a Samsung Q1 tablet computer, connected to my steno machine via Bluetooth. So I can sit in the back of the room, reading the display from my laptop, and the student can carry the tablet around wherever they need to go. It's especially good for lab and studio classes, and for anything that requires a lot of mobility. I've occasionally even put my steno machine on a shoulder harness and walked alongside my client while they carry the tablet and converse with friends or colleagues.
