With the AirLiner™ WS100 wireless slate you can interact wirelessly with your computer, SMART Board™ interactive whiteboard or Sympodium™ interactive pen display from up to 52’ (16 m) away. The battery-free tethered pen allows you to control software programs, write notes, and highlight information in digital ink. Multiple slate users can write at the same time as someone at a SMART Board interactive whiteboard.
I have had this for a few years but it has only been used a few times. It has a replacement power supply. It's prime use is in education - not as I had intended.
Original Instruction manual is included, though full documentation etc is still available from SMART TECHNOLOGIES, as are up-to-date drivers etc.
