&gt; definitely one of my favorite devices of 2016<p>These devices are at least 3 years old.<p>Honestly, the fact that I can only erase the whole board and not a small section is a deal breaker for me. As is the form factor.<p>Make them as big as a small whiteboard, add local erase features and they&#x27;ve got a winner.<p>While we&#x27;re at that, they could manufacture boogie board whiteboard replacements. That would be a hit in all teaching institutions. Imagine: No more markers or chalk. One click erase.
